Claims that black is invalid as a formatter

The dev container linter claims that "ms-python.black-formatter" is invalid as a value. I believe it's valid, however. (It seems to work)

This should likely be filed on the dev container extension (I will move it to the correct repo). The extension registers a formatter on activate using registerDocumentFormattingEditProvider.

I also see this when editing .vscode/settings.json, so not sure that it should only be a dev container issue?

Having the same issue. I'm not running a dev container just plain vscode.

I am having a similar issue with yapf but via SSH Remote. Black doesn't throw an error but just doesn't do anything. Yapf throws an error:

Yapf works fine locally on my Mac, but when I install on the remote, it throws an error:

Extension 'yapf' is configured as formatter but it cannot format 'Python'-files
