I've had this issue with both the 8.x-4.x and 8.x-1.x versions of Page Manager.

I can go through the UI, and select a context for use of a page variant, but cannot save. Basically, the save button is unresponsive. In checking the console logs, this is what I see:

An AJAX HTTP error occurred.
HTTP Result Code: 500
Debugging information follows.
Path: /admin/structure/page_manager/manage/test_page_3/variant/test_page_3-panels_variant-0/contexts/add/entity%3Anode_type?ajax_form=1
StatusText: Internal Server Error
ResponseText: {}

Below is a screen grab of what I see when this fires:

Turned on error logging on my build, and this is the result I'm getting:

Drupal\Component\Plugin\Exception\ContextException: The 'entity:node_type' context is required and not present. in Drupal\Core\Plugin\Context\Context->getContextValue() (line 71 of /[my site install]/core/lib/Drupal/Core/Plugin/Context/Context.php).

I'am having the same issue when I try saving an added FIELD context.

Uncaught PHP Exception Drupal\\Component\\Plugin\\Exception\\ContextException: "The 'entity:field_config' context is required and not present." @ core/lib/Drupal/Core/Plugin/Context/Context.php line 71

Any1 having the same issue and a working solution?

I had the same issue and found this is related to Page manager contexts ajax broken callback
My bad, I got this error too after applying the patch in the link

I checked it a bit more and found that the error is cause because Page Manager uses 'entity:node_type' as ID for the context. However, ctools expects contexts starting with 'entity:' to be an actual entity instance instead of a type.
It is some design issue here but I don't have enough insight on this to help further.

Note:
If you just want to add the node_type (e.g. article) as a context variable to be used by a custom module then you can select String in the select control and set a custom value for this purpose.

@piggito So, this may be a feature request, then, and not a bug?

BTW, how did you find out about how the error was occurring?

@karolus I do think it is a bug because the module is not correctly integrating with ctools for this case.
I found the cause by debugging the module and comparing with other contexts which work OK.

@piggito, thanks for the alternative solutions. As for your reply above:

If you just want to add the node_type (e.g. article) as a context variable to be used by a custom module then you can select String in the select control and set a custom value for this purpose.

How is this accomplished? I tried a few things, but so far, not working.

I'm leaving this open so people will know what's going on, but this isn't a bug with Page Manager. Like @piggito said in #5, it's a bug with CTools. See the parent issue.

@dcam I can confirm that--with the patch to the linked CTools issue, the site is working as it should. Test environment: Drupal 8.5.0 running PHP 7.0.

The patch from https://www.drupal.org/project/ctools/issues/2696819 allows me to add the context, but when I hit 'Update and save' it fails and gives the following error:

Drupal\Core\Config\UnsupportedDataTypeConfigException: Invalid data type for config element page_manager.page_variant.test_page-panels_variant-0:static_context.path.value in Drupal\Core\Config\StorableConfigBase->castValue() (line 213 of core/lib/Drupal/Core/Config/StorableConfigBase.php).
