Anyone running into issues launching Orion from the latest prefect 2.7.4 docker image? My container is crashing on with these logs (check thread for logs), thanks @User for pointing it out

Hi Amruth. Sorry to hear that. Are you able to move your traceback to this thread please, to help keep the main channel tidy?

I just tested with the latest Docker image -

prefecthq/prefect:2.7.4-python3.10

- and was able to run a flow fine using

DockerContainer

- with Prefect Cloud. I see you’re trying to use Orion. I’m not familiar with that error.

Regarding the SQLAlchemy warning: Upgrading to the latest SA version will resolve it.

That error is an issue with a database migration

Notably:

No such revision or branch ‘f7587d6c5776’

That database migration cannot be found. Are you connecting to an existing database?

Yes, I was trying to connect to an existing PostgreSQL DB

Hm, so the migration is https://github.com/PrefectHQ/prefect/blob/c660a3f13c07cc4c3c2a0b341c32ef4e49a1a667[…]/postgresql/2022_11_24_143620_f7587d6c5776_add_worker_tables.py

I’m very confused that it’d be “missing” here

I've no idea why it didn't work for me this morning, it seems to spin up just fine now.
