Unknown configuration tag

[gdobreva]

Hello,

I am using dune to compile my code, but unfortunately for every file, I get several unknown configuration tag errors from ocamllsp
(for example:
Unknown configuration tag "INDEX" ocamllsp
Unknown configuration tag "INDEX" ocamllsp
Unknown configuration tag "INDEX" ocamllsp
Unknown configuration tag "SOURCE_ROOT" ocamllsp
Unknown configuration tag "UNIT_NAME" ocamllsp).

I have tried fixing it, but none of the solutions I found on other threads helped.

Hi @gdobreva, thanks for the report.
Unfortunately there is no recent release of ocaml-lsp-server that would mute these errors for OCaml 4.13.

Would you be able to migrate your project to OCaml 4.14 ?
Another workaround would be to use an older version of Dune that does not write these tags into the server's configuration.
