Re: Unable to log to stdout for pgadmin4 in python3

I don't think that's possible with FileHandler in python.

The workaround is to change the logging FileHandler to StreamHandler, If
you have access to pgAdmin4 source code in docker then you can try
replacing below line (File: *<YOUR_DOCKER_PATH>*
/pgadmin4/web/pgadmin/__init__.py),

fh = logging.FileHandler(config.LOG_FILE, encoding='utf-8')

with

fh = logging.StreamHandler(sys.stdout)
