Hi all,

We've migrated from Odoo 13 to Odoo 17 and everything went fine. But we are now noticing that when we try to edit new products on the front-end through the Webeditor it gives the following error:

UncaughtPromiseError > OwlError

Uncaught Promise > Something that is not an Error was thrown in onMounted (see this Error's "cause" property)

OwlError: The following error occurred in onMounted:

Caused by: RPC_ERROR: Odoo Server Error

This only happens for products that not yet have any content added to them in the building blocks area of the product page. We have been able to edit products after the migration, but we can't seem to pinpoint when this issue started or what caused it.

Does anyone know what causes this and how we can fix this issue?

Thanks!
