Error while finding module in VS code debugger

I have tried different solutions to enable me to debug a python file in my project.
Here is my file structure:

project-main

-ns

-examples

and several Python files in examples and ns. Basically, all example files are using ns or other imported modules. I also have a conda environment that I have already activated in vs code terminal. And here is my launch.json file:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python Module",
            "type": "python",
            "request": "launch",
            "module": "project-main.examples",
        }
    ]
}

I select Start debugging from the Run menu but I keep getting this error:

E+00000.063: Error determining module path for sys.argv

             Traceback (most recent call last):

Based on the information you provided, I provide a possible answer. If your module project-main is located under the workspace, you can try the following way.

If you didn't set cwd, default would be the root directory of the file. During the debugging process, the module cannot be found. You can set cwd in the launch.json file by add the following codes:

"cwd"："${workspaceFolder}"

Here is the correct config:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Module",
            "type": "python",
            "request": "launch",
            "module": "examples.run_this",
            "justMyCode": true
        }
    ]
}

so basically for the module field, I have to enter the name of the subfolder that includes the main running file (run_this) and then the name of the running file.
