Civicrm version: 5.45.1 Drupal 9.3.3

Adding (or editing an existing) civirule where the selected trigger is "webform is submitted" generates the fatal error:

CiviRule trigger class "CRM_WebformCivirules_Trigger" does not exist

excerpt from the Drupal log:

$Fatal Error Details = array:3 [ "message" => "CiviRule trigger class "CRM_WebformCivirules_Trigger" does not exist" "code" => null "exception" => Exception {#3523 #message: "CiviRule trigger class "CRM_WebformCivirules_Trigger" does not exist" #code: 0 #file: "///public_html/sites/default/files/civicrm/ext/org.civicoop.civirules/CRM/Civirules/BAO/Trigger.php" #line: 166 trace: { ///public_html/sites/default/files/civicrm/ext/org.civicoop.civirules/CRM/Civirules/BAO/Trigger.php:166 { CRM_Civirules_BAO_Trigger::getTriggerObjectByClassName($className, $abort = true) › › throw new Exception('CiviRule trigger class "' . $className . '" does not exist'); › } }

Other rules are working fine, only the 'webform is submitted' trigger fails. I've not been able to find any information on this error.

Can anyone help?

  • is it possible the 'webform submitted' trigger was built for d7 webforms and you are trying it with d9?

  • I've thought this might be the issue, but I don't know how to test or work out if it is.

  • create the simplest possible webform in both D7 and D9 and compare outcomes?

  • then open an Issue via lab.civicrm.org/extensions/civirules/-/issues and at least have helped by reporting the error even if you can't fix it

Perhaps work around by using another type of trigger, eg if the webform adds a tag, or adds them to a group
