Resolve Odoo Client Error When Trying to Open Landed Cost Menu (Uncatch Promise Error)

Looking for an expert in Odoo who can help me resolve an error I am encountering when trying to open the landed cost menu. I am currently using Odoo 16 on Odoo.sh. The error message is an uncatch promise error Cannot read properties of undefined (reading 'relation'). I require someone with extensive expertise in Odoo to help me resolve this issue urgently.

Here is the error logs:

Uncaught Promise > Cannot read properties of undefined (reading 'relation')

TypeError: Cannot read properties of undefined (reading 'relation')
