Error when 'create group' permission is set on authenticated user

Can you reproduce this with beta2?

Okay so then forgive me for assuming the problem is in either Bootstrap or your subtheme's code. Could you XDebug your way through the error to see where it is coming from?

This must be a Group issue per the warning: group_content_field_data.gid IN ()' cannot be empty.

The Bootstrap base theme does not intercept or modify module DB queries.

Indicating that it works in one theme but not another is not sufficient enough of a "test" to blame any theme.

That being said, this sounds more like a byproduct of the [lack] of a _theme: ajax_base_page router option, which was ultimately resolve by #2745953: AjaxBasePageNegotiator should not require _theme: ajax_base_page to be specified.

Thanks for clearing that up Mark!

@thronedigital Can you confirm this issue is resolved when using Drupal 8.2.0?

Right, let's accept this as a bug then, seeing as it occurs in Bartik.

Not caused by a theme

That may be so, I changed the title to indicate it doesn't occur in all themes.

Sure, I get that. I just took it a step further by removing the specific theme names. It made it appear as if it was an issue caused by both Bartik and Bootstrap code rather than simply appearing in both. There are many times when themes are simply innocent bystanders to issues that need fixing deeper in the system, hence my comment in #7. Surprised that the core bug fix didn't also remedy this one. Was pretty sure that's what the issue was.

I've tried to reproduce this with Drupal 8.2.2 and failed. Can you confirm that it is fixed with that version of core?

I'm seeing this issue in a bootstrap subtheme but not when switching to bootstrap itself as my main theme. Drupal 8.2.5. Still debugging, will update!

Also, it is NOT occurring for me in Bartik.

Have you found anything new yet as to what makes this error happen?

I'd like to add that this error is triggered when using Automatic Entity Label

D8.2.7
Group 8.x-1.0-beta5
and Automatic Entity Label latest dev which corresponds to 8.x-2.0-beta1.

As I have also reported here, because I think it is connected to token support, too: https://www.drupal.org/node/2774827#comment-12021840

Creating a node using https://www.drupal.org/project/auto_entitylabel

[node:group:id] [node:group:label]

Causes 2 errors:

Drupal\Core\Database\InvalidQueryException: Query condition 'group_content_field_data.entity_id IN ()' cannot be empty. in Drupal\Core\Database\Query\Condition->condition() (line 71 of /../core/lib/Drupal/Core/Database/Query/Condition.php).

Drupal\Core\Entity\EntityStorageException: Query condition 'group_content_field_data.entity_id IN ()' cannot be empty. in Drupal\Core\Entity\Sql\SqlContentEntityStorage->save() (line 770 of /../core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).

The problem with the errors reported here is that something is triggering the retrieval of GroupContent entities by the entities they represent (entity_id base field), without specifying what IDs to filter on. Seeing as this occurs in various weird situations that cannot be easily reproduced, I doubt that it has anything to do with auto_entitylabel.

Unless someone has steps to reproduce this issue without failure, we cannot fix this. So please either:

1. Use XDebug or other means to tell us the full stacktrace
2. Go to simplytest.me and try to reproduce the results there, posting back here with steps to reproduce

I enabled "All messages, with backtrace information" under logging.
Hope that helps. XDebug would take more time ... let me know.

You should be able to reproduce this by using the automatic entity label:

The error appears once it is enabled on a node type and goes away once it is disabled.

In your case, it's the patch in the other issue that's broken. It tries to load GroupContent entities for an entity that hasn't been saved yet. Maybe we can/should fix this in Group to prevent people from making the same mistake.

Wow, you are really fast!
And I have to mention: Group is THE ONE module that has been terribly missing in Drupal for years! Thanks for building it!
