Specified argument was out of the range of valid values.

Problems

No problems have been detected in the workspace so far.

[ericsnowcurrently]

Thanks for letting us know about this, @ebubekirtrkr. Where are you seeing that message? Is it a pop-up notification in VSCode or is it in one of the output panels? What is in the "Python" output panel? What about the "Problems" panel? Also, are you using Jedi or the new language server? (i.e. what is "python.jediEnabled" set to; more info #3977)

Note, you left out a bunch of helpful details that we asked for in the issue template. I've pasted the template into the issue above, so please make sure it is filled out. Thanks!

[ebubekirtrkr]

I have added a little more information. Also when I turn "python.jediEnabled" on, problems not occurs.

[ericsnowcurrently]

Thanks. So this appears to be a problem with the language server. I'm going to send the the issue over to them.

[jakebailey]

How did {workspaceFolder} make it to us without having a replacement done by the extension or VS Code? {workspaceFolder}/~/ itself is very strange. @ebubekirtrkr Have you modified extraPaths?

[ebubekirtrkr]

@jakebailey I have placed it in there, because I don't wanna share my directory path.

[jakebailey]

Oh, I see. That's nearly the same syntax as what's in the config.

Note that I don't think putting ~ in the config is going to work; ~ is typically expanded by a shell, but not in other cases. If you could share what your extraPaths is (even if it's partially redacted), then I'd be happy to give you an alternate method to try.

[jakebailey]

Actually, in context, /~/ doesn't quite make sense either.

[ebubekirtrkr]

@jakebailey I edit it as what it was at beginning.

[jakebailey]

We had some recent fixes around paths and Python 2.7. I'd appreciate it if you could try out our daily build by setting the following and reloading:

"python.analysis.downloadChannel": "daily"

[ebubekirtrkr]

@jakebailey When I copy and paste it in settings , a notification occurs in problems section which is Unknown configuration setting. Also, in VSCode settings there is no python.analysis.downloadChannel option.
What I need to do?

[jakebailey]

You can safely ignore the message. It's undocumented, and we give it out to help people test things.

[ebubekirtrkr]

@jakebailey I have added what you say in settings and I reloaded VSCode. But It seems unsolved.

[jakebailey]

Those google-cloud-sdk paths, did you set up some configuration in order to add them? As in extraPaths or PYTHONPATH?

[ebubekirtrkr]

Yes in settings.json there is an option.

"python.autoComplete.extraPaths": [
    "~/google-cloud-sdk/platform/google_appengine/lib/webapp2-2.5.2",
    "~/google-cloud-sdk/platform/google_appengine",
    "~/google-cloud-sdk/lib",
    "~/google-cloud-sdk/platform/google_appengine/lib/endpoints-1.0",
    "~/google-cloud-sdk/platform/google_appengine/lib/protorpc-1.0"
],

[jakebailey]

That's probably where things are going wrong. Nothing between those settings and our use of it expands the ~ into your real $HOME. (See also #557.)

What you can try is making those paths absolute. Based on your previous logs, I'd say something like:

"python.autoComplete.extraPaths": [
    "/home/ebubekirtrkr/google-cloud-sdk/platform/google_appengine/lib/webapp2-2.5.2",
    "/home/ebubekirtrkr/google-cloud-sdk/platform/google_appengine",
    "/home/ebubekirtrkr/google-cloud-sdk/lib",
    "/home/ebubekirtrkr/google-cloud-sdk/platform/google_appengine/lib/endpoints-1.0",
    "/home/ebubekirtrkr/google-cloud-sdk/platform/google_appengine/lib/protorpc-1.0"
],

Note that we have other issues when it comes to the ordering of these paths; some of those may not end up working due to the way we carve out parts of folders as import roots. You may need to reorder the above deepest-first, like:

"python.autoComplete.extraPaths": [
    "/home/ebubekirtrkr/google-cloud-sdk/platform/google_appengine/lib/endpoints-1.0",
    "/home/ebubekirtrkr/google-cloud-sdk/platform/google_appengine/lib/protorpc-1.0"
    "/home/ebubekirtrkr/google-cloud-sdk/platform/google_appengine/lib/webapp2-2.5.2",
    "/home/ebubekirtrkr/google-cloud-sdk/platform/google_appengine",
    "/home/ebubekirtrkr/google-cloud-sdk/lib",
],

The exception seems to happen deep in .NET framework. See https://github.com/dotnet/corefx/issues/34359. It is fixed in 3.0 while we are on 2.2.

[MikhailArkhipov]

We have upgraded LS to .NET Core 3.0 a while ago in #1521
