Following the advice I received in Allow only existing CiviCRM contacts to create own Drupal account, I'm trying to implement Drupal Rules to create an associated Drupal user whenever a CiviCRM contact is added to the 'Web Site Users' group.
I'm running Drupal Core 7.66 and CiviCRM 5.12.3. Trying to get this working I've installed Entity API 1.9, Rules 2.12, and CiviCRM Entity 2.2.
This is the rule I'm using:
Creating a new contact in CiviCRM is correctly creating a new Drupal user, but I'm also getting this error, with no other visible consequences:
Notice: Undefined property: CRM_Contact_DAO_Contact::$contact_id in civicrm_entity_contact_user_get() (line 3671 of /var/sites/c/civicrm.jesusshapedpeople.net/public_html/sites/all/modules/civicrm_entity/civicrm_entity.module).
Should I be concerned? Am I doing something wrong? Is there a fix?
