Describe the bug When using lsp-python-ms, I run the command xref-find-references emacs shows: eror The path is empty. (Parameter ’path’) When using pyls, it 's all ok.

To Reproduce In a python file, use lsp-python-ms and run the command xref-find-references or lsp-ui-peek-find-references

Expected behavior list all the references

Which Language Server did you use lsp-python-ms-20200223.2136 languageServer.0.5.45

OS manjaro kde spacemacs

Can you provide file to reproduce the issue with?

Can you provide file to reproduce the issue with?

Any python file that has function/variable/class references in my case!

When I set lsp-log-io to t and run the command lsp-find-references ,then I get this! It seems the argument that lsp sends to Microsoft LanguageServer is not right!

After I reinstall my spacemacs, the problem disappears!
