How can I set the logging level of the prefect graphql service? I tried adding both

PREFECT_SERVER__LOGGING__LEVEL: WARN

and

PREFECT__LOGGING__LEVEL: WARN

environment variables to the docker-compose file, however I still see

INFO

log messages.

Maybe try

PREFECT__LOGGING__LEVEL: WARNING

Neither

PREFECT__LOGGING__LEVEL: WARNING

nor

PREFECT_SERVER__LOGGING__LEVEL: WARNING

seemed to have the desired effect
