Problem description
After a machine failure I am reinstalling NeoVim, LazyVim.
I added omnisharp via Mason.
When I open a cs file I get this warning:
Warn 12:36:17 notify.warn ...m/3834/usr/share/nvim/runtime/lua/vim/lsp/_transport.lua:68: Spawning language server with cmd: `{ "omnisharp", "-z", "--hostPID", "60960", "DotNet:enablePackageRestore=false", "--encoding", "utf-8", "--languageserver", "FormattingOptions:EnableEditorConfigSupport=true", "Sdk:IncludePrereleases=true" }` failed. The language server is either not installed, missing from PATH, or not executable.
The language server is installed in ~/.local/share/nvim/mason/packages/omnisharp and I do not have any further config related to omnisharp.
I have pinned mason at version 1.*.
I can start the language server manually and that works without any problem or message.
LspStart omnisharp
Expected behavior
language server starts without warnings, errors
Steps to reproduce
Install NeoVim
Install LazyVim
Install omnisharp via Mason
Open a c# project
