Expected behaviour

Works normally

Actual behaviour

Hit the exception: NoneType' object has no attribute 'additional_info'

.vscode\extensions\ms-python.python-2020.11.371526539\pythonFiles\lib\python\debugpy_vendored\pydevd_pydevd_bundle\pydevd_additional_thread_info_regular.py", line 125

Steps to reproduce:

Not sure how to repro it. It suddenly stopped working. What I did - I added the line into the code that should throw an exception, and created handlers that would catch it but they don't. Instead, if I debug the code, I have that exception.

XXX

[KathRains]

I also found that Python interpreter is probably set up wrong and can't fix it. Please see the screenshot below.

If I set up "justMyCode": false in launch.json, I immediately hit some exceptions in Python installed somewhere else (no in env).

My settings:

{

    "python.testing.unittestEnabled": false,
    "python.testing.nosetestsEnabled": false,
    "python.testing.pytestEnabled": true,
    "python.testing.pytestArgs": [
        "tests"
    ],
    "python.pythonPath": "venv\\Scripts\\python.exe"
}

But when I click the select interpreter it pretends it doesn't recognize it:

[fabioz]

Have you tried putting the full path in python.pythonPath to see if it helps?

As for the 'NoneType' object has no attribute 'additional_info', can you provide the logs when this happens?

i.e.:

• Open VS Code
• Select the command Extensions: Open Extensions Folder
• Locate the Python extension directory, typically of the form ms-python.python-2020..***
• In that directory ensure you do not have any debug*.log files, if you do, please delete them
• Go back into VS Code and modify your launch.json to add the setting "logToFile": true, see below:

{
    "name": "Python: Current File (Integrated Terminal)",
    "type": "python",
    "request": "launch",
    "program": "${file}",
    "console": "integratedTerminal",
    "logToFile": true
}

• Start debugging
• When done, go back into the extension directory and upload the debug*.log files into this GitHub issue.

[KathRains]

@fabioz Thanks for your response. Yes, I tried. The same result.
But what I found is I have this exception only when I have FLASK_DEBUG = 0 in my launch.json. As soon as I set it up to 1, no exceptions anymore. I will try to provide logs.

[fabioz]

As a note, I'm waiting for the logs... or at least the full stack trace (as it is, I just know that None was passed as the thread when trying to get the debugger info from the thread, but there are many places that call into it, so, it's hard to track down without the full stack trace -- which the logs should show).

So, given that this report is currently not actionable and further info wasn't provided, I'm going to close the request.

@KathRains Please reopen when/if you're able to provide the logs.

[KathRains]

Hi, sorry for the delay, here are logs, in zip file. Please remove them out from the git after you download them if possible because they may have some sensitive information (even although I checked and cleaned files). Thanks. I don't know how to reopen the issue though (I think it's not possible for me because I didn't close it).

[fabioz]

Thanks for the info. I've just reopened the issue.

[fabioz]

Can you do one check for me?

In the file:

c:\Users\user\.vscode\extensions\ms-python.python-2020.12.424452561\pythonFiles\lib\python\debugpy\_vendored\pydevd\_pydev_bundle\pydev_monkey.py

In line 919 (inside the if thread_id is not None:)

if you add

py_db.disable_tracing() -- right before py_db.notify_thread_not_alive(thread_id)

Does it stop giving that error?

[KathRains]

Let me try

[KathRains]

Okay, it looks like the exception has gone after I added that line. At least, I don't see any information in the terminal.
