We’re almost there! After changing Edit > Preferences > Debugger > Connection from the default “a system provided free port” to 9000, and launching via Debug > Run without Debugging, I can debug.
I also changed Edit > Preferences > Debugger to always accept a requested debugging connection, because it was painful to have to accept each request to the GAE server.
But, I get a Komodo warning with each request:
C:\Program Files (x86)\ActiveState Komodo IDE 8\lib\support\dbgp\pythonlib\dbgp\client.py:1909: RuntimeWarning: Parent module ‘dbgp’ not found while handling absolute import
How should I resolve that?
