I try to create a contact in CiviCRM 5.9.1 with a Webform and Webform CiviCRM Integration (all in Drupal 8.6.7),
But when I choose the needed fields in CiviCRM and I use the ENABLE TAGS AND GROUPS FIELDS : no field appears.
If I still save then I get in Drupal an
Error: Class 'Drupal\webform_civicrm\CRM_Core_BAO_Tag' not found in Drupal\webform_civicrm\FieldOptions->get()
To recover the use, I need to delete the Webform. All of the other fields appears and can be selected in the Webform : Phone, Email, etc.
Is this, reveals a bug in Webform CiviCRM Integration or could it be something wrong in the Tags and Groups ?
Also if I select Yes for Tags and Groups fields, then impossible to get fields for Phone, Email, etc.
