Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.Hi,
when I try to visit any of the invitation settings pages, I'm getting this error:
InvalidArgumentException: Class "\Drupal\webform\Controller\WebformController" does not exist. in Drupal\Core\DependencyInjection\ClassResolver->getInstanceFromDefinition() (line 24 of /siteroot/core/lib/Drupal/Core/DependencyInjection/ClassResolver.php).
When I remove the _title_callback in het webform_invitation.routing.yml file, the error is gone (and of course I do not get titles for my admin pages)

broonAre you going to work on a better solution? If not, please do not assign yourself to this bug.
Apart from that, which Webform version are you using?
Comment #4
kyberman@Paul Webform did few changes during last releases, so I'll try to bring better patch and we should update minimum version constraint.
Comment #5
broonThat was my guess and that's why I was asking for the module version used.
As long as Webform doesn't have a stable release, each update may break Webform Invitation.

kybermanThese problems started with webform version 8.x-5.0-beta20, where WebformController was replaced by more specific WebformEntityController. Patch attached.
Comment #7
kybermanPatch merged into dev. Going to create beta3 with note about compatibility.
