Hi guys I am starting a prefect v1 server. However I get an error message like this in the docker logs of the graphql service:

tmp-graphql-1  | Running Alembic migrations...
tmp-graphql-1  | 
tmp-graphql-1  | Could not upgrade the database!
tmp-graphql-1  | Error: Can't load plugin: sqlalchemy.dialects:postgres

Does anyone have any insight about this?

Have you tried

from prefect_sqlalchemy import SqlAlchemyConnector

?
