I have the same sourceror warnings in my lsp logs (running in neovim). No matter what folder I remove (including the mix cache directory as you suggested), the warning keeps coming back. But the LSP works, so it’s not breaking anything for me. In addition to the final warning as shown before, I also have several of these warnings preceding:
warning: redefining module Sourceror (current version loaded from ~/.local/share/lvim/mason/packages/elixir-ls/sourceror-0.11.2.ez/sourceror-0.11.2/ebin/Elixir.Sourceror.beam)\n lib/sourceror.ex:1\n
(this warning is repeated for a few Sourceror modules).
It’s not clear to me, @la_219, what the observed malfunctioning is, except from the warnings.
