I am getting this error:

an exception was raised:

Any clues what might be causing the problems? Or how to find the culprit?

For more context - this happens inside “Codium”, where the LS is involved.

I did all I could think of. mix deps.unlock --all, mix deps.update --all, mix deps.clean --all followed by the regular mix deps.get

In general when I see this it means I need to mix deps.get in the project.

I am sorry I should have mentioned that I did all the deps related “tricks” I could think of:

mix deps.unlock --all , mix deps.update --all , mix deps.clean --all followed by the regular mix deps.get

Normally I delete /deps and /_elixir_ls folders and it fixes it.

I already tried deleting deps and _build earlier, and it didn’t help. But thanks to your response I found the hidden .elixir_ls directory and removed it - > bingo! That cured the problem. Thanks a lot.

Lol, at this point I just delete that directory proactively every time I update anything.

Same btw, and I had no ElixirLS troubles in years by doing so. :smiley:
