WSOD when trying to add new Mapping

We're also seeing this error with Authorization - Group 8.x-1.0 when trying to add a group.

Possibly related modules installed:

• Drupal Roles Authorization 8.x-1.0-beta6
• LDAP Authorization Provider 8.x-4.3
• Group (group) 8.x-1.5

I need to investigate further, and will post more info when I have it.

Hi @ Andy-Inman and bioschaf,

Is the issue sporadic or consistent?

authorization, authorization_group, and ldap have all been updated since this was reported. Does the issue

I am unsure if this is a problem with the authorization module or authorization_group module. I am the maintainer of both.

Hi @bluegeek9

This is from memory - the issue was on a client site that I'm no longer involved with...

* Is the issue sporadic or consistent?

Consistent, but there's some kind of trigger - it typically worked the first time. The site had a lot of group mappings set up (30+ maybe). Adding a mapping worked the first time, but no more.

ISTR that it would return to a working state after config export/import, even though a new mapping could have been added.

I did a bit of investigation, and concluded that something was invalid/broken in the FAPI structure obtained by ajax updates triggered by the the "add" button.

In the end I added a work-around - using a form_alter hook, added a number of empty rows to the form before display. With that it was possible to add new mappings.

Hope this info is of use, right now I'm not working with this module.

I think a blank mapping in the schema could have caused this. It was fixed. I will leave this open if someone else experiences the problem.

Automatically closed - issue fixed for 2 weeks with no activity.
