I'm getting an error whenever I try to save set up a computed field in odoo 14 Enterprise Edition.

This happens for every field I try to compute, no matter how simple the script is.

Any ideas, why this happens?

Example

model: stock.move.line

dependencies: qty_done

code:

for record in self:
  record['x_qty_done_new'] = record.qty_done * 2

Traceback

Error:

If a "module" is necessary for backwards compatibility, use
`odoo.tools.safe_eval.wrap_module` to generate a wrapper recursively
whitelisting allowed attributes.

Pre-wrapped modules are provided as attributes of `odoo.tools.safe_eval`.
