mail.IMMUTABLE_OBJECT error when deleting notebook document folder
I'm currently experiencing a mail.IMMUTABLE_OBJECT error when I try to delete a "notebook" document folder.
It looks like this folder is a trace of older releases, and is not to be used, as it was shared, and every document put there from a shared account just makes the document disappear. Hopefully, when logging with the owner of the folder, we can get back the document.
What should I do?
Below is the complete error:
An unknown error (mail.IMMUTABLE_OBJECT) has occurred.
msg: cannot modify immutable object: 12
