[Support] error when Send email from workflow with attach

[Tpeterburger]

What's your question or issue?

Hello,
I'm using Paperless-NGX in a docker on Synology.
Everything works as requested except for sending emails from the workflow.
I tested the workflow trigger and it works correctly.
In action 1, a label, path, and owner are applied.
In action 2, an email is scheduled to be sent.

If the email contains only text, everything is fine.
If "Add attachment" is checked, the email is not sent.

In the logs, here is the error:

[paperless.handlers] Error occurred sending notification email: [Errno 2] No such file or directory: '/usr/src/paperless/media/documents/originals/0000861.pdf'

The actual file name is incorrect (0000861.pdf), and the specified folder exists, but it doesn't contain any files. Only subdirectories named after the storage paths are listed.
What can I do to fix this problem?
Thank you for your help.

If you don’t want to wait you can use the dev docker tag but I wouldn’t stay on it for too long, in general dev can sometimes have unstable changes
