@AaronHForgeFlow, Thank you for the feedback! You are right, the error occurs because order is not always a string. I will update the code to check if order is a string, and if not, set it to "" before passing it to _search: This will prevent the TypeError and make the method robust for all internal Odoo calls. Let me know if you have any other suggestions!
