How do I configure monaco-languageclient to enable Client Capabilities for python LSP?

[Taco7]

I am trying to hookup a monaco editor with a python lsp server. Currently using Palantir's LSP along with the sample client .

The only feature which seems to be working as of now are the code suggestions but additional features like hover and jump to definition are not. The client is not able to process the response given by the server. I am attaching a snippet of the network messages, but I am not sure how do I resolve this. Request-Response

You probably need your file to exist on the filesystem, and not use "inmemory://" scheme

Why is the "inmemory://" scheme not possible

It is expected that the language server process has access to the same file system as the client.

For instance, the client sends the textDocument/didSave notification, and the server needs to have access to the filesystem to get the new value of the file
