Fatal error: Argument 1 passed to picture_get_mapping_breakpoints() must be an instance of PictureMapping

Should be fixed by #2273249: Upgrade issue 1.3 to 2.0, a new verson will be released today.

I installed version 2.1 and still have the same issue as reported here:

Argument 1 passed to picture_get_mapping_breakpoints() must be an instance of PictureMapping

Did you specify a picture mapping on the field settings?
Did you ran update.php?

same error..

Error message
Recoverable fatal error: Argument 1 passed to picture_get_mapping_breakpoints() must be an instance of PictureMapping, boolean given, called picture.module on line 367 and defined in picture_get_mapping_breakpoints() (line 1059 of picture.module).
The website encountered an unexpected error. Please try again later.

it is new install and not upgrading from previous version.
uninstall and enable again module , same error .

Can you check the field settings and if necessary save them again, if that does not help, read on

Line 366 ($picture_mapping = picture_mapping_load($display['settings']['picture_mapping']);) is getting the field settings, if this fails it returns false, hence the error on line 367.

To debug you could add dpm($display); as the first line in that function, if you get a white screen, add return; on the next line (part of the devel module). The dpm should show an array with an element settings, and inside an element picture_mapping

Output of dpm should look similar to

array (
  'label' => 'hidden',
  'type' => 'picture',
  'weight' => '1',
  'settings' => array (
    'picture_mapping' => 'sas_inline_picture',
    'fallback_image_style' => '',
    'image_link' => 'colorbox',
    'colorbox' => 'sas_content_standaard',
  ),
  'module' => 'picture',
)

I must mention, that my error appeared when using within Views as a field "Picture"

#9: your settings do look correct, views is given a problem with me as well (Fatal error: Nesting level too deep - recursive dependency? in /data/disk/o1/static/sas/includes/common.inc on line 7530), I'll check later today

#10: picture_group is old and should disappear after saving the settings, can you test a plain node view to see it works?

PS: I wish I was at DrupalCon but alas

"Notice: Undefined index: picture_mapping in picture_field_formatter_settings_form() (line 245 of /Users/jstoller/Sites/californiasciencecenter.org/www/sites/all/modules/contrib/picture/picture.module)" should be fixed

I tested the following, so far so good:

• regular node view
• node view using display suite
• view of nodes using content, display suite, rendered entity and fields mode
• file entity (admin/structure/file-types/manage/image/file-display) using picture and viewing the file
• field collection item connected to a node (and using display suite on field collection), node displays ok
• view of field collection items using rendered entity and fields
• view based on file entities, all display modes
• bean block using a file field and rendered file formatter (using picture)

Just to be sure, you did clear all caches, and you could try drush cc views as well, or even drush rr

Another possible solutions, edit and save all your picture mappings

I did use update.php and cleared the caches but still the same error.
Tried new dev version as well.

timlie: you have it while displaying a node? Did you re-save the picture mappings?

I disabled the module and even uninstalled it so I don't have any picture mappings anymore.
Still I get the error.

Thanks!

Timlie i assume you created a new one and assigned on the display formatter?

At first I just did an upgrade to version 2 of the module (I had picture mappings).
The error appeared.
I disabled the module now and uninstalled it as well. Now I have no picture mappings anymore but the error is still there.

timlie: can you create a new mapping and try it using an image field on a node? Make sure the select the mapping after setting the output formatter to picture

I created a mapping but still when I visit a non admin page I get on every page the error. The rest of the page doesn't load.

I've re-saved all my breakpoints and it got rid of all but one of the Fatal errors.

The remaining error is associated with one View where Flexslider is used, which I currently cannot configure, as I get the following error when I click on 'Settings'

An AJAX HTTP error occurred.

The table flexslider_picture_optionset doesn't exist (although table flexslider_optionsetis there). So with this problem, I'm still having WSOD on non-admin pages.

* EDIT *

My missing table is due to previous patches applied addressing #2084979: flexslider_picture broken on/after flexslider -alpha3.

brb

File displays and field formatters are fixed in the latest dev version. The flexslider issues will be addressed in #2084979: flexslider_picture broken on/after flexslider -alpha3

Re-opening the issue.
The upgrade path is still broken. I have the same error message as reported by jstoller, using the latest dev, the error still remains. I first upgrade from 7.x-1.3 to 7.x-2.1, and now to 7.x-2.x-dev. For the sort term, please describe on how to get out of this situation. But we need a solid upgrade path because currently it is badly broken.

@jstoller, this is not related to the module, but to drupal.org's packaging script. I downloaded and unpacked the dev-release the 'old-fashioned' way.

Erik did you use the git version or the dev version?

The dev version contains the latest changes now.

@attiks, I used the dev release (sometimes I'm only human ;) ). The current dev release fixes the problem. Thanks so much!

Thanks, I'll create a new release in a sec

I'm still seeing this issue with the 2.3 release. I just started to use the picture and breakpoints module yesterday on a new installation local site. I started with the Bootstrap 3 theme, and did not see it work. So, today I started to use an Omega sub-theme. The error only shows on the home page, but the node pages are not being responsive. I started out with 2.0, updated to 2.2 today, and noticed you just released 2.3. I disabled the picture and breakpoint modules and uninstalled. Removed my test image styles, and then reenabled the picture and breakpoint theme. Created the breakpoints, generated the image styles using the large (480) image styles. Edit the new image styles to various settings, mapped the picture settings for the breakpoints to the appropriate image styles. Assigned the Article image field to picture using my new picture mappings group. Still seeing the error on the home page.

If you need I can start with a fresh install and database to help?

Which is correct? From picture module project page:
You have to order your breakpoints from the "largest" to the "smallest", but keep in mind that it depends if you use min or max queries, the picture element (and the polyfill) will use the first matching source tag.

From breakpoint module project page:
It is incredibly important to order the Breakpoints correctly before creating any Breakpoint groups.

Breakpoints need to be arranged from smallest to largest (from top to bottom). E.g. "mobile" at the top and "wide" below it.
If you create a Breakpoint group with the Breakpoints in the wrong order, the group becomes "locked" to the order that the Breakpoints were set in at its creation and your responsive images will not render properly.
If you find yourself in this situation, you should delete the broken Breakpoint group and re-create it after you've set your Breakpoints to the proper weighted order.

Can you paste your error message?
Starting from scratch might be a good idea

I am starting from scratch. I updated my first post with a question about the order of the breakpoints. What is the correct order? Mobil to Wide as breakpoint module suggests, or largest to smallest as the picture module suggests? I'm using an Omega sub-theme if that matters.

UPDATE: I started from scratch. I am not getting the error. However, using the mobil first order the pictures are not being responsive. I think this is because the mobile media query (min-width: 0) is matched first. I think I also need to set a max-width parameter on the breakpoints, or perhaps order from largest to smallest order as the picture module suggests, but the breakpoint module cautions against.

Picture will use the first match, so when using min width make sure the smallest is last, when using max width make sure smallest is first.

BTW you don't have to delete the breakpoint group, you can re order them and save, next you have to re save the mapping

Working. I tried to reorder and save, but the old order returns after I loaded the node again. I needed to change the order in the theme.info file also i think. So, I think the picture module is correct about the order from "largest" to "smallest", but all of the examples and videos have it wrong. There are several ways to fix this I think: order largest to smallest using min-width media queries. Order smallest to largest using max-width media queries?? Include both the min and max width in the media query?

Since this is all a little new to me, I guess I didn't recognize a solution right off.

You're right you have to change them in the theme, or override them first using the UI. Theme is the better approach.

I user aegir stack from omega8.cc. I just upgaded my entire site (via migration). During the courese of this upgrade I upgraded Picture module from 7.x-1.2 to 7.x-2.4 and I am getting this error. I cannot even access any page of the site so there is no way reordering any mapping or doing anything else. I cannot log in to the site. I there a certain upgrade process that should be followed fro picture 1.x to 2.x. I tried the 7.x-2.x+3-dev too but to no avail.

@jstoller , I have a feature which may have picture_mappings I will check that. But, I have many content types with each having few core image fields and they have picture_group as mapping in their displays. How would that get handled in upgrade.

I tried it. I have one feature with only one of its file making a single mention of the word picture_group. I changed this instance of picture_group to picture_mapping ran drush fr , drush cc all. The fatal error is still there preventing me from doing nything. The content of the file that contantained word picture_group (now edited) is:

I disabled the feature but still no change. There is no documentation on upgrade process???

The update process is just running update.php or drush updb, did you try running drush updb on the migrated site to see if all updates are processed?

What kind of error do you get?

@attiks, yes did drush updb again after migration despite the migration process itself runs drush updb to upgrade the site from one platform version to other. The error I am geeting is:

Recoverable fatal error: Argument 1 passed to picture_get_mapping_breakpoints() must be an instance of PictureMapping, boolean given, called in /data/disk/c1/static/mop-prod-7.28.1-p001/sites/all/modules/contrib/picture/picture.module on line 528 and defined in picture_get_mapping_breakpoints() (line 1364 of /data/disk/c1/static/mop-prod-7.28.1-p001/sites/all/modules/contrib/picture/picture.module).

Just getting WSOD.

Do you have the same problem if you do a manual update to picture 2?

I havent' tried manual update. I can try that. Is it possible to downgrade picture to 1.x and the manually upgrade to 2.x.

@jstoller thanks!!! Your advice #56 fixed the fatal error and I can now see the site. I don't know how the picture_mapping was empty even though in the previous version of the site picture_group was showing selected in the UI.

Closing this, in case of problems open a new issue
