I would highly appriciate any help on this. Since we are upgrading the whole system to D9 and lastest civicrm, at the moment it is not possible to upgrade this module.
We have a webform created using webform_civicrm 8.x-5.0-beta8 running on Civicrm 5.39.1 and Drupal 9.8.20.
Upon submission an error is preventing it from full submission.
Form has been working for months perfectly well, but now we ecounter this error upon submission.
The website encountered an unexpected error. Please try again later.
Drupal\Core\Entity\EntityStorageException: Invalid Relationship in Drupal\Core\Entity\Sql\SqlContentEntityStorage->save() (line 846 of core\lib\Drupal\Core\Entity\Sql\SqlContentEntityStorage.php).
The form submits to civicrm Case type while pulls and prepopulates the data of current submitter along with optional to submit three co-submitters, which are empty when form loads.
As I have seen through basic debugging, even when all co-sumitter(s) fields are left empty webform still tries to make api calls to create their relationships i.e. wf_civicrm_api('relationship', 'create', Array) .
