I have a strange problem where ocaml-lsp-server won’t compile, with the following :
#=== ERROR while compiling ocaml-lsp-server.1.17.0 ============================#

After reading the log, this seems to be the relevant part :

For some extra context, read this post. I’m not sure it’s what’s causing my problem in this case, however.
All help is appreciated
