@yuvipanda, I think maybe this FIXME:

pangeo-forge-runner/pangeo_forge_runner/commands/base.py

Lines 187 to 188 in 506616a

	# otherwise). FIXME: No extra comes out here, just message
	self.log = logging.getLogger()

is why this log line

https://github.com/pangeo-forge/pangeo-forge-runner/actions/runs/3156980724/jobs/5137303685#step:7:303

{'message': 'Using Any for unsupported type: typing.Callable[[typing.Any], NoneType]'}

only has a "message" field? If so, is there anything to be done about it? If not, why does this line not have a "status"?
