AttributeError: ‘Meta’ object has no attribute ‘_table_fields’

Can’t figure where this error is coming from. Frappe version is 14.26.1

I also had the same error when using the latest version of the frappe-helm release ( erpnext-6.0.18) .

I downgraded to version 6.0.16 and everything works as expected

Note: I used version 6.0.16 for no particular reason
