I try create a paper format for a report template, I have this error message:
odoo.tools.convert.ParseError: "null value in column "name" violates not-null constraint
DETAIL: Failing row contains (959, null, ir.actions.report, null, null, report, list,form, 1, 2021-03-12 17:35:13.849794, 1, 2021-03-12 17:35:13.849794, null, qweb-pdf, null, null, null, 77, null, null, null).
The code that I wrote is this:
