Unable to log to stdout for pgadmin4 in python3

[Glen Huang]

Hi,

I’m running pgadmin4 in docker, and I have set LOG_FILE = '/dev/stdout’ to log 
to stdout, but when running pgAdmin4.py, it fails with:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/pgadmin4/pgAdmin4.py", line 56, 
in <module>
    app = create_app()
  File "/usr/local/lib/python3.6/site-packages/pgadmin4/pgadmin/__init__.py", 
line 183, in create_app
    fh = logging.FileHandler(config.LOG_FILE, encoding='utf-8')
  File "/usr/local/lib/python3.6/logging/__init__.py", line 1030, in __init__
    StreamHandler.__init__(self, self._open())
  File "/usr/local/lib/python3.6/logging/__init__.py", line 1059, in _open
    return open(self.baseFilename, self.mode, encoding=self.encoding)
OSError: [Errno 29] Invalid seek

I think it has something do with this:

Is there any way to work around it so I can make pgadmin4 log to stdout?

Regards
