Unexpected response from Language Server

[masterSunflowers]

Hi, thank for great repository. I currently encounter this problem:
Unexpected response from Language Server: None. Here is the log from multilspy: bash INFO:multilspy:{"time":"2025-01-14 11:43:11","level":"INFO","caller_file":"C:\\Users\\thieulvd\\AppData\\Local\\anaconda3\\envs\\continue\\Lib\\site-packages\\multilspy\\language_servers\\jedi_language_server\\jedi_server.py","caller_name":"start_server","caller_line":99,"message":"Starting jedi-language-server server process"} INFO:multilspy:{"time":"2025-01-14 11:43:11","level":"INFO","caller_file":"C:\\Users\\thieulvd\\AppData\\Local\\anaconda3\\envs\\continue\\Lib\\site-packages\\multilspy\\language_servers\\jedi_language_server\\jedi_server.py","caller_name":"start_server","caller_line":103,"message":"Sending initialize request from LSP client to LSP server and awaiting response"}

I don't know where to start debugging.

Dear @masterSunflowers , can you please run the unit tests for multilspy as shown in README and report the results?

[masterSunflowers]

Yes, of course. But now, I have no access to the computer that I encountered the problem. I will test and report soon (about a week later)

Hi @masterSunflowers, did you have a chance to look into the issue? I would be glad to help in any way I can!

@LakshyAAAgrawal Receiving similar error. Though not always. In my quick test: I'm getting the error 8 times out of 36 when trying to resolve this file: https://github.com/aws-samples/aws-serverless-airline-booking/blob/archive/src/backend/booking/src/notify-booking/notify.py

Note that I've tried running this multiple times and I'm have the same failures consistently.
I have tried replicating it directly on Python REPL using SyncLanguageServer. Same result.

could you please try the recently integrated pyright language server instead of Jedi to see if it solves your issue?

@LakshyAAAgrawal Upgraded to 0.0.15 (the latest version). Still the same error. (fwiw, I'm not sure if pyright was included in the release.)
