TypeError: call_user_func(): Argument #1 ($callback) must be a valid callback

Setting as major because it breaks existing sites using defined groups coming from 1.x.

I found the same errors when upgrading from 1.5 to 2.1, It happens when associating content to group for a group_content type configured previously.

The culprit is residual configuration set in (for example for blog content type) : "core.base_field_override.group_content.blog-group_membership.uid" , it sets:

status: true
dependencies:
  config:
    - group.content_type.blog-group_membership
id: group_content.blog-group_membership.uid
field_name: uid
entity_type: group_content
bundle: blog-group_membership
label: 'Group content creator'
description: 'The username of the group content creator.'
required: false
translatable: false
default_value: {  }
default_value_callback: 'Drupal\group\Entity\GroupContent::getDefaultEntityOwner'
settings:
  handler: default
  handler_settings: {  }
field_type: entity_reference

So when getting the callback to obtain uid in https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Field%21F... things get broken.

The same may happen for group uid as there is this conf:

status: true
dependencies:
  config:
    - group.type.blog
id: group.blog.uid
field_name: uid
entity_type: group
bundle: blog
label: 'Group creator'
description: 'The username of the group creator.'
required: false
translatable: false
default_value: {  }
default_value_callback: 'Drupal\group\Entity\Group::getDefaultEntityOwner'
settings:
  handler: default
  handler_settings: {  }
field_type: entity_reference

This was set in https://git.drupalcode.org/project/group/-/blob/8.x-1.x/group.install#L495 so I guess that this residual configuration must be removed when upgrading to group 2 or 3.

I have tested what's done in MR, removing the config using this script with drush:
(If anyone would test it make a backup of all items of core.base_field_override.group.*.uid, they will be removed)

/**
 * @file
 */

/**
 * Removes base field definitions that was set in group v1
 * to obtain the default value callback.
 */
function group_update_9211() {
  $config_factory = \Drupal::configFactory();
  foreach ($config_factory->listAll('core.base_field_override.') as $config_name) {
    $base_field_override = $config_factory->getEditable($config_name);

    if ($base_field_override->get('field_name') !== 'uid') {
      continue;
    }

    switch ($base_field_override->get('entity_type')) {
      case 'group':
        $class = 'Drupal\group\Entity\Group';
        break;

      case 'group_content':
        $class = 'Drupal\group\Entity\GroupContent';
        break;

      default:
        continue 2;
    }

    if (
      $base_field_override->get('default_value_callback') === $class . '::getCurrentUserId' or
      $base_field_override->get('default_value_callback') === $class . '::getDefaultEntityOwner'
    ) {
      $base_field_override->delete();
    }
  }
}

group_update_9211();

I'm encountering the same error with group^2.1, but my Drupal version is 10.0.9. I would greatly appreciate any suggestions or guidance on how to address this situation.

We have the same on our page so we need to wait for the fix and stay with 1.5.

The reason for this is the setting "The group creator automatically becomes a member" within the group type with the issue #3364226.
So, if you are creating a new group of this type it will try to add the user to the individual role which not exists/can not be configured.

Next to the fix you will have two possibilities:
1) Uncheck the "The group creator automatically becomes a member"
2) Create a Role called "Admin" with the individual member setting

Hello all. I have just looked at the MR and tested it on our system. It works and everything looks good! Thanks!

I think this should not delete the config overrides, they exist for a reason, but it should update the default value. node module has an example for this:

/**
 * Updates stale references to Drupal\node\Entity\Node::getCurrentUserId.
 */
function node_post_update_modify_base_field_author_override() {
  $uid_fields = \Drupal::entityTypeManager()
    ->getStorage('base_field_override')
    ->getQuery()
    ->condition('entity_type', 'node')
    ->condition('field_name', 'uid')
    ->condition('default_value_callback', 'Drupal\node\Entity\Node::getCurrentUserId')
    ->execute();
  foreach (BaseFieldOverride::loadMultiple($uid_fields) as $base_field_override) {
    $base_field_override->setDefaultValueCallback('Drupal\node\Entity\Node::getDefaultEntityOwner')->save();
  }
}

To cover both the classname change and the method rename, I think it's safe to just leave out the default_value_callback definition.

I'll create a separate MR to do that change instead.

Ok, opened https://git.drupalcode.org/project/group/-/merge_requests/106.

We're on core 9.5.10 and using groups 2.2.0 and I've tried the patch attached but I still get the same issue when I try to save content with an image. I'm using groupmedia module, so it might be related.
I'm wondering if we might need a similar patch on groupmedia as well.

What's the *exact* message you get? This should fix it for all group_content bundles.

This is the message I got @berdir:

I had the wrong entity type in the query, it should work now, but you'll need to run the update again or run the code in a different way. Or manually update the config.

All good, seems to be working now, thanks @berdir.

Get a same/similar error when a user wants to join into a group. Even when I apply the MR of #12 as patch.

The website encountered an unexpected error. Please try again later.

Hello @berdir , how can i apply your modification in my project? beacause i dont see any patch to apply it
Thx

Merge request 106 worked. As Berdir wrote, it's only working, if you apply the patch before upgrading from groups V1 to V2. Perhaps it's possible to re-trigger the db actions as part of the patch again?

My merge request is against V2, use that, not the patch.

@drupal_developer2022, you should see various links to https://git.drupalcode.org/project/group/-/merge_requests/106 on automated comments and issue summary above. and if you then append .diff, like https://git.drupalcode.org/project/group/-/merge_requests/106.diff, then you can download and save that as a patch.

@berdir it works for me thanks!

Is there a chance to get this in a new, stable release for group?
We are still on version 1.5 because of this issue.

We need to switch because we moved to PHP8.2

@berdir, the patch works for me and solved this issue, thanks. One thing that might help someone, the .diff file wouldn't apply, but when I went to the merge request page and downloaded the .patch file, it applied.

For info, merge request 106 worked for me too.
Config: Drupal 10.2.3, Group 2.2.2.

hi,

I am also facing the same issue after upgrading the group module.
After adding the group, though, I no longer see the issue, but the created groups do not appear on the Group list page.
Please suggest.

Is working for me since a few months.
I think we can change to RTBC

Can also confirm this did the trick for us

Can confirm that it works fine, attached patch from MR 106.
