I think this is just related to the Existing Contact" component which I'm assuming gets populated when adding the `webform_civicrm` handler. ``` CRM_Core_Exception: One of parameters (value: ) is not of the type CommaSeparatedIntegers in CRM_Utils_Type::validate() (line 469 of /app/vendor/civicrm/civicrm-core/CRM/Utils/Type.php). Civi\Api4\Service\Spec\Provider\EntityTagFilterSpecProvider::getTagFilterSql(Array, '`a`.`id`', 'IN', Array, Object, 0) (Line: 593) Civi\Api4\Query\Api4SelectQuery->createSQLClause('`a`.`id`', 'IN', Array, Array, 0) (Line: 569) Civi\Api4\Query\Api4SelectQuery->composeClause(Array, 'WHERE', 0) (Line: 464) Civi\Api4\Query\Api4SelectQuery->treeWalkClauses(Array, 'WHERE') (Line: 304) Civi\Api4\Query\Api4SelectQuery->buildWhereClause() (Line: 156) Civi\Api4\Query\Api4SelectQuery->getSql() (Line: 171) ``` For `civicrm_contact` component, there are a bunch of default entries that have properties with empty keys. ``` '#no_autofill': '': '' ``` I think it's only complaining about `#tag` but we need to make sure each property should be like `'#no_autofill': { }` instead.
