Hi ,

@sharmankita what exactly is the issue that you are facing?

Is your code working fine locally? Are there error logs for the same?

@aravindvnair99 Nope not getting errors on local, When I enable debug mode on local it is showing me same logs normally in colors. but IDK why it is printing it in stack driver as error.

Are you sure you sure not logging to stderr? I have a similar issue with logging from Go binaries and I think Google Logging falls back to error log level when it's unable decipher what the level is. Maybe structured logging helps in this case

(Great profile picture :))

I am not logging anything manually.. When I enable debug logs express is printing logs like below screenshot.

Thanks :) @weyert

I understand but can you check the labels in Google Logging for one of the log entries whether you don't have something like this in labels the value logName: "projects/my-project/logs/stderr". That would mean it picked it up the messages from the stderr stream which are alway marked as errors.

If not, you might want to consider structured logging to make sure Google Logging picks up the correct log level. I have to admit I wouldn't know how to that for the debug-package, though. This is one of my personal pain peeves with Google Logging
