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):
  File "/home/neil/.virtualenvs/default/lib/python3.9/site-packages/pygls/protocol.py", line 152, in deserialize_message

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.

Config...

(use-package lsp-mode

  :defer t
  :config
  (setq lsp-idle-delay 0.5
	    lsp-enable-symbol-highlighting t)
  :commands (lsp lsp-deferred)

  :config
  (with-eval-after-load "lsp-mode"
    (add-to-list 'lsp-disabled-clients 'pyls)
    (add-to-list 'lsp-enabled-clients 'jedi)))

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.

..and tried opening a .py file without having any virtualenv activated and get the same error stemming from pygls and pydantic...

    raise JsonRpcInvalidParams()
pygls.exceptions.JsonRpcInvalidParams: Invalid Params

Which is the same error, albeit the files are under ~/.local/lib/python3.9/site-packages/ rather than ~/.virtualenvs/default/lib/python3.9/site-packages/.

As this is a problem stemming from types in pygls do you think I should report upstream?

@slackline perhaps it should be opened at pappasam/jedi-language-server
