Updating a relational field and clearing it is throwing a "Something went wrong" error message.
Ex: Say there is a Genre relational field (one-to-one relation with itself), first selecting fiction and then changing it so sci-fi. Upon clearing it is throwing the message. "Woops something went wrong, please try again"

Steps to reproduce the behavior

• Create collection “Genre”
• Add relational field called “parent”. this field is “one-to-one relation” with the same “Genre” collection.
• Click on fiction
• Again click on fiction-drama
• Clear the selection

Expected behavior

It should clear the selection without any errors.
