I have a OneNote which has powerautomate emailing a link to updated pages twice a day. It has worked fine for months then yesterday it failed with the error Error; unknown error code encountered when attempting to retrieve notebook details. Code: 20269. I cannot find what the issue is or reference anywhere to this error code.

The notebook is on a Sharepoint library, it has not moved and has run succesfully for months. If i change the target notebook in the automation to another OneNote in the same library it works.
