Actual behavior

As discussed offline, I’m preparing to use the new debug.getLauncherCommand api as described here: https://github.com/Microsoft/vscode-python/issues/3121 in conjunction with the Azure Functions extension. I specified the launcherCommand manually just to make sure it would work like this:

"languageWorkers__python__arguments": "/Users/ericjizba/.vscode-insiders/extensions/ms-python.python-2018.9.2/pythonFiles/experimental/ptvsd_launcher.py --client --host 127.0.0.1 --port 9091"

But I get this error in the logs for the func cli:

Awesome that works for me! Any changes to the debug.getLauncherCommand api based on this?

I will note that the traceback is misleading as that code doesn’t exist in https://github.com/Microsoft/vscode-python/blob/master/pythonFiles/experimental/ptvsd_launcher.py . Either the copy you are working from is old (are you running against the development build of the extension), or something else is going on.
