Response status "OK" expected, but "NO" received. (Mailbox name should probably be prefixed with: INBOX.)

Hi all

do you know this error?

600
Skipping virtualenv creation, as specified in config file.

This part is the important, I think: imap_tools.errors.MailboxFolderSelectError: Response status "OK" expected, but "NO" received. Data: [b'Client tried to access nonexistent namespace. (Mailbox name should probably be prefixed with: INBOX.) (0.001 + 0.000 secs)

But I don't use the folder name INBOX but Paperless instead. And INBOX must exist due to the fact that I cannot create it.

My compose is:

    hostname: email2pdf
    environment:
     IMAP_URL: "${EMAIL_SERVER}"
