[error] Bad RPC call to node nextls-runtime => LSP Exited => :timeout

[teamon]

This happened a few times on a different occasions but now it happens every time I restart vscode.

The relevant log lines seems to be these:

Removing .elixir-tools and restarting everything fixes the problem.

i haven't actually seen that error in a prod build, only in tests

14:44:06.623 [error] Bad RPC call to node nextls-runtime-1715431446385794000@MacBook-XXX: {:EXIT, {:badarg, [{:ets, :lookup, [:elixir_config, :parser_options], [error_info: %{cause: :id, module: :erl_stdlib_errors}]}, {:elixir_config, :get, 1, [file: ~c"src/elixir_config.erl", line: 21]}, {:elixir_compiler, :string, 3, [file: ~c"src/elixir_compiler.erl", line: 7]}, {Module.ParallelChecker, :verify, 1, [file: ~c"lib/module/parallel_checker.ex", line: 112]}, {Code, :compile_file, 1, []}]}}

i think its a weird timing issue, will investigate further, thank you for the report!

[teamon]

I'm constantly hitting this issue now. I've run next-ls locally over tcp but there are no logs or errors in its output.

Is there any way I could debug this locally?

[mhanberg]

@teamon I think this should fix it: #478

[teamon]

I'll give it a try, thanks!

[mhanberg]

last release got botched, re-doing it now

[mhanberg]

should be fixed now
