Server initialization failed

[bjornasm]

Connecting to host over SSH, and got this error message. Got it before and completely uninstalled mypy (on both host and client machine) + restarted vscode to fix. However, at nest login I got the same errors.

I have no clue how to debut this further. The error messages is repeated five times untill it refuses to connect to server.

Upgrading from 1.3.0 to 1.9.0 on the mypy installed in venv did not change this behaviour. However updating typing_extensions in the venv seems to have solved it, following this issue: microsoft/vscode-black-formatter#378

Probably an issue with not up to date dependencies?
