After updating to v2 and v3 automatically my service has been interrupted and my application does not work


There may be a better way as Fly keep adding stuff however you can revert to a prior version. Check out:

Or if you have it working locally, I would assume a new deploy (using that working code) would also work on Fly. I can’t see why not, assuming e.g all the secrets/environment variables it expects are present. That’s a nice thing about using Dockerfile based images: you should be able to recreate the same locally.
