Troubleshooting Alembic Revision Error in Phoenix Deployment

·Sep 11, 2024 04:40 PM

when I'm trying to deploy a new release of phoenix I got this error during server start up: `alembic.script.revision.ResolutionError: No such revision or branch '3be8647b87d8'` Does anyone know what might be the issue?

The error alembic.script.revision.ResolutionError: No such revision or branch '3be8647b87d8' indicates that Alembic cannot find the specified migration revision. This could be due to a missing or incorrect migration file.According to the migration file, the revision 3be8647b87d8 should add token columns to the spans table. Ensure that this file exists in your src/phoenix/db/migrations/versions directory.Would you like more detail on how to resolve this issue?Sources: - migration file
💡 Hint: Mention RunLLM in the thread for followups.

Hey Xiaohan W., this error is an indication that you ran a more recent version of Phoenix containing this particular migration and then downgraded the version of Phoenix you are running to a version that did not contain this migration. The error should disappear if you run the latest version of Phoenix.

I deployed the newest version and all the previous traces are gone. Do you know what might be the reason?

Hi Xiaohan W., I would guess you have connected to a new database. Did you deploy with Postgres or SQLite?
