User matching query does not exist on upload after upgrade from Paperless

[shtrom]

Hi,

I've just migrated from the-paperless-project/paperless@ec1d132 (2.7.0-179-gec1d132) to a docker setup using jonaswinkler/paperless-ng latest de901ac006dd at the moment).

After fixing previous issues with Websockets in nginx (#1077), I restarted from scratch, and recreated a container based on the pristine data from paperless.

On first start-up, it ran all the migrates. I can log in and see the current documents. I can also see two users: consumers and paperless (which I didn't create manually, it's just there, with id 2). I have renamed consumer to something else, as I intend to keep using it as the non-admin user.

I am now trying to upload a document, from the dashboard, but I'm consistently getting error User matching query does not exist, regardless of which user I'm logged in as when trying to do so.

I have the following stack trace:

I'm not sure which User it's trying to find, but doesn't.

Both my users are here

$ sqlite3 data/db.sqlite3 'select * from auth_user;'
1|XXX|2021-06-03 07:33:17.356936|0|user|||0|1|2020-09-17 12:34:50|
2|XXX|2021-06-03 07:33:54.812949|1|paperless|||1|1|2020-09-17 12:53:38.094647|

Who is that missing user?

Paperless expects to have a "consumer" user. This user does not even have to have a password (the default "consumer" user does not have one).

🤦🏼 Thanks.
