So I am trying to create a lot, so far the code works in my odoo community version on local development. But when I deploy it on odoo sh, it keeps saying Record does not exist for product.

Notes:
1. The product exists. I have a separate endpoint listing and getting the product.
2. I tried changing user access, the error is the same. 

On local development with community version odoo, I can't replicate it. The error shows only when I have deployed it to odoo sh.
I need help. Thank you.

                ref = product.default_code

          # Create a new lot

            lot = request.env['stock.lot'].sudo().create(lot_data) 

            lot_serializer = Lot()
