Here is the API response: {“errors”:[{“message”:“Unexpected Error”,“operation”:“return_create”,“field”:“return_create”,“request_id”:“6908a807f98f1f4474d2e30c”,“code”:22}],“data”:{“return_create”:null},“extensions”:{“throttling”:{“estimated_complexity”:10,“cost”:10,“cost_detail”:{“return_create”:{“items_count”:0,“cost”:10,“total_cost”:10,“fields”:{}}},“user_quota”:{“credits_remaining”:4004,“max_available”:4004,“increment_rate”:60}}}}

Please find the error I am getting from dashboard:

Error! Failed to Generate RMA. ‘NoneType’ object has no attribute ‘assigned_warehous
