I use a Repeater field in my RelationManager and have setup a Pivot class for this table which should cast the repeater field to an Array. Sadly whenever i want to edit the relation that i saved with repeater data to beforehand, it will give me the error "foreach() argument must be of type array|object, string given". I have casted it on the Pivot table, tried multiple ways on the merged Models aswell, it won't do anything.
It's also wrongly casted via tinker, seen in the Screenshot.
