Errors in taiga-back and taiga-async

[MinnML]

Hello,
I had a taiga docker instance running just fine for couple of years (either 6.4 or 6.5 version). But now, I get errors accessing the instance. I see two errors in the log file and am not sure how to deal with them.

Error 1:

I had the same problem and no idea what caused it.

After some searching I stumbled over this https://stackoverflow.com/a/66068299.

1. Remove the deployment using docker compose rm
2. Remove the taiga network docker network rm taiga-docker_taiga
3. Redeploy ./launch-taiga.sh && docker compose logs -f
4. ...
5. Profit
