I am trying to live debug a Python Google App Engine Standard application in Stackdriver Debug console. When I click on a deployed file (main.py) and the line where I want it to break, I get an error message stating "Multiple modules matching" and lists a couple files with the same name.
This is a new deployed version with that filename being unique in my project. I wouldn't expect it to see multiples of the same filename. Because of that error, I am unable to debug the deployed app.
The debugger loops through all the loaded Python modules in the project and may find a file with the same name. When multiple files are listed, copy and paste the full path to the file you are wanting to debug.
Example: apps/[PROJECT]/[VERSION.UNIQUE_ID]/myfile.py:[LINE_NUMBER]
You can copy the full path from the file listed in the error message.
