Sumneko lua-language-server failed to load

Question

My OS is openbsd 7.2 with neovim v0.7.2. I am using the repo at https://github.com/amy-juan-li/nvim-lua.git to configure Neovim.

There is a problem with the neosolarized.rc.lua file.

Can anyone see what the invalid character is?

I have included the file below. Also installing lua-language-server throws this error:

error="Could not find which release file to download.
Most likely the current operating system or architecture is not supported (OpenBSD_amd64)."'

There's a snippet of the mason log is below.

Is there no way round this ? If any more file or log Information is needed please let me know.

When I start nvim I get this startup error

init.lua is loaded!

Answer 1

Try to use setup instead of init_lsp_saga.

There was a breaking change.
