Cannot unset environment variables in launch configuration

[brechtm]

The Launch.json attributes section of the VSCode documentation mentions that the env atttribute of a launch configuration supports unsetting variables by using the null value.

This doesn't seem to work for Python launch configurations:

• it doesn't undefine variables when running a program
• an error dialog is shown when debugging a program (or test in my case):

  Invalid message: "env"["ELECTRON_RUN_AS_NODE"] must be str

Yep, it's not supported at the moment. #93 is tracking this.

Note that this doesn't work when running (versus debugging) either. I don't know if that is also handled by debugpy or not.

[int19h]

It does - running without debugging is debugpy running with "noDebug": true, and environment handling is the same in that case.

Thanks for the clarification. I asked because I don't get the Invalid message: "env"["ELECTRON_RUN_AS_NODE"] must be str error when running (no debug).

I had a go at implementing this, but I didn't get far, unfortunately...
