Language servers exits

[slackline]

Hi,

I'm trying to use jedi-language-serveralong with lsp-jedi.

I have jedi-language-serverinstalled under a virtualenv and activate it within Python (via pyvenv-workon) and then try opening a .pyfile. Unfortunately it exits with the message....

Server jedi:12920/starting exited with status exit(check corresponding stderr buffer for details). Do you want to restart it? (y or n)

And I can't ever get it to start. *jedi::stderr* shows the following...

Process jedi stderr finished
Traceback (most recent call last):

I've reinstalled pyglsundet the virtualenv and its on 0.11.3 with pydantic pegged at 1.8.2 (since pygls requires < pydantic-1.9.0).

I have no problem starting jedi-language-serverat the command line under the same virtualenv.

Any advice on how to solve this would be very gratefully received and if I can supply any more information to help debug please let me know.

Thanks.

You should open this issue with https://github.com/fredcamps/lsp-jedi. I don't personally use that client and we haven't yet ruled out whether the issue is with your configuration of that client

Apologies will post there and see if it can be resolved, thanks for the pointer @pappasam

As suggested I opened an issue for this with lsp-jedi and as suggested installed jedi-language-server outside of the virtualenv but with the same result.

Kindly redirected back to jedi-language-server.

Is there anything I can do to investigate if it is my configuration of jedi-language-server that might be causing this problem?

Also, as it seems to stem from a typing error in pygls I'm wondering if this should be reported up-stream to them.
