Can't get elixir dialyzer warnings and erros anymore

Hi,

On my vscode, I didn’t change anything but I don’t get the warning anymore in my code, ElixirLS is installed as always and here is the settings:

Also there was a file called : .elixir_ls , I’m not able to generate it anymore (any commands ?)

Update 1 : I can’t see the extension in the Tasks list on the output section (terminal)

Thanks

Installed versions :

Erlang/OTP 24 [erts-12.2] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [jit]

Elixir 1.13.1 (compiled with Erlang/OTP 22)

This folder has to be there otherwise Elixir-LS is not running.
I assume you did restart VSCode?

I got the folder now, but no warnings as usual

hard to say, never had such an issue.

do you have “dialyzer_…” files in .elixir_ls folder?
Do you see logs like [Info - 1:50:11 PM] [ElixirLS Dialyzer] ... in the output-window in VSC?

It shows me this now (after reinstalling ElixirLS and restarting)

Yes I see the logs now, and I have the folder “dialyzer_tmp”

So anything helpful in the logs?

Elixir and OTP do not match! Fix that.

I have no idea how to do it, i just installed Elixir a few months ago.

Is there some commands to make coherant ?

Elixir doesn’t require to be compiled with the same version of OTP as it’s used with, for as long as it’s compatible (see Compatibility and Deprecations — Elixir v1.13.4)

Benjamin is right, thats most likely not the cause of your problem.
But it does not hurt to have an up-to-date version installed (there are some known dialzyer issues with early OTP 24 versions). The best way is using asdf, see Installation — nerves v1.9.0

Do you have anything in the logs?
