Arg override error with Python slash testing framework and vscode Debugger

Question

I am trying to debug slash testing framework test using vscode.

slash run -o perf.ip=1.2.3.4 perf\test_perf.py -vvv

My launch.json looks as follows:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "slash testing",
            "type": "python",
            "request": "launch",
            "module": "slash.frontend.main",
            "args": [
                "run",
                "-o",
                "perf.ip=1.2.3.4",
                "-vvv"
            ],
            "console": "integratedTerminal",
            "justMyCode": false,
            "cwd": "${workspaceFolder}\\code\\scripts\\python"
        }
    ]
}

When I debug the file, i get the following error in the terminal:

ERROR: slash.app: Unexpected error occurred
Traceback (most recent call last):
  File "C:\Python37\lib\site-packages\slash\app.py", line 119, in __enter__

    "Invalid path: {0!r}".format(path))
confetti.exceptions.InvalidPath: Invalid path: 'perf.ip'
ERROR: Unexpected error: Invalid path: 'perf.ip'

Is something misconfigured here? Running the slash command on cmd line works just fine but errors out on the the vscode debugger.

Answer 1

Resolved. After adding the file name AFTER the run arg in the list, it works fine. Seems like running through the vscode debugger/launch, the args are position dependent.

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "slash testing",
            "type": "python",
            "request": "launch",
            "module": "slash.frontend.main",
            "args": [
                "run",
                "perf\\test_perf.py",
                "-o",
                "perf.ip=1.2.3.4",
                "-vvv"
            ],
            "console": "integratedTerminal",
            "justMyCode": false,
            "cwd": "${workspaceFolder}\\code\\scripts\\python"
        }
    ]
}
