[BUG] Lsp server terminated immediately after launch

[hek14]

I am tyring to use distant.nvim for remote work. It is a really nice plugin. But there is an issue in my setup: after I DistantOpen /path/to/server/file.py, I can see some diagnostic show up but the server is terminated quickly, I check the distant.log, which says that ".../nvim-data/lazy/distant.nvim/lua/distant-core/client.lua:195: Client terminated: "INVALID_SERVER_JSON"".

commands that I use:

• DistantLaunch ssh://USER@SERVER_IP:PORT
• DistantOpen /path/to/server/file.py

Related:

• platform: I have tried on windows/mac as local machine, and linux as remote machine. Both has the same issue.
• distant version: 0.20.0, I also tried 0.20.0-alpha.10, the same issue.
• distant.nvim version: v0.3
• lsp server: pyright/clangd (both of them failed with the same problem)
• distant.nvim config:

            require('distant'):setup(
              {
                  servers = {

                          lsp = {

                                  -- cmd = {'/usr/bin/pyright-langserver', '--stdio'}, -- I have tried both of the two "cmd"

                                      print(prefix .. ' LSP exited with code ' .. tostring(code))

                                      -- Signal can be nil
                                      if signal ~= nil then
                                          print(prefix .. ' Signal ' .. tostring(signal))
                                      end

                  }
              } 
             )

I also have the same issue for python as well, I also tried the "fix/AddCheckForFailingToStartLspClient" which results in no LSP client being attached.
