Error "step is not defined' when debugging in Visual studio code

[nathalok]

When I tried to debug a mocha test in Visual Studio Code its throwing the following error -
ReferenceError: step is not defined

Below is the copy of my launch.json file used for debug configuration and that should reproduce the error

Had the same thing, need to split the args into separate strings otherwise strings with spaces are wrapped in double quotes.

"args": [                                
   "${workspaceFolder}/test/MyTests/sampleTest.js",                                
   "--require",
   "mocha-steps"
],
