Import of documents with ASN failed

[hpz24]

Hi,
I had to move a paperless installation from one cloudron server to another (+ new subdomain if this is important: from dms.domain1.com to dmsp.domain2.com).
Move means backing up on cloudron1 and restoring on cloudron2.

After that, app started without error. Login was possible, all documents are still there and also import of document works - UNLESS there is a QR code with an ASN number at the top of the document.
Then I get the following error in Paperless logs (and also in the app):

Is there something missing?
Thanks!

Are you using some plugin for QR ASN?

[BrutalBirdie]

OOM?
Can you check if the new Paperless installation has the same RAM allowance comapred to the old one?

No, there is no special plugin. I justed added (or uncomment) the specific options in the paperless.conf.

I checked my installation: The app had already 4GB, I changed to 6 and tried it again. Works.
So maybe the solution was really "Add more RAM if problem exists"
Thx
