Using the gcloud console for Google App Engine results in a runtime error from metrics

Question

I am trying to use the gcloud console through a browser. When I clone my repository and start the dev server, I get a runtime error from the indicators:

$ dev_appserver.py $PWD Traceback (most recent call last): File "/google/google-cloud-sdk/platform/google_appengine/dev_appserver.py", line 101, in <module> _run_file(__file__, globals()) File "/google/google-cloud-sdk/platform/google_appengine/dev_appserver.py", line 97, in _run_file execfile(_PATHS.script_file(script_name), globals_) File "/google/google-cloud-sdk/platform/google_appengine/google/appengine/tools/devappserver2/devappserver2.py", line 1041, in <module> main() File "/google/google-cloud-sdk/platform/google_appengine/google/appengine/tools/devappserver2/devappserver2.py", line 1037, in main dev_server.stop() File "/google/google-cloud-sdk/platform/google_appengine/google/appengine/tools/devappserver2/devappserver2.py", line 845, in stop metrics.GetMetricsLogger().Stop() File "/google/google-cloud-sdk/platform/google_appengine/google/appengine/tools/devappserver2/metrics.py", line 117, in Stop total_run_time = int((Now() - self._start_time).total_seconds()) TypeError: unsupported operand type(s) for -: 'datetime.datetime' and 'NoneType' 

I do not call the metric module directly or use it in any other way. How to disable it in the console or in the code so that I can run the application normally?

It works fine locally through the SDK.

Answer 1

Indicators

dev_appserver.py was recently added to the Cloud SDK version 144.0.0 for users who refused to install https://console.cloud.google.com , is also used to use these indicators.

In response to this message, we added additional logic to prevent this erroneous error message in the future. This update will appear in a future release.

Answer 2

I got this working by resolving the problem in my app.yaml file, one of my routes was not specified correctly.

Fixing this route with a leading slash and avoiding the dot in the route regex also seems to fix the error:
