[RLS] Nothing happens on hover

[Ploppz]

I installed LanguageClient-neovim as in the Quick start page (exact same configuration)

I installed RLS with: rustup component add rls-preview rust-analysis rust-src

When I call :call LanguageClient_contextMenu() and select "Hover" or "TypeDefinition", nothing happens. Not even a message.

When I select "Implementation" I get [LC] Error: Failure { jsonrpc: Some(V2), error: Error { code: InternalError, message: "An unknown error occurred", data: None }, id: Num(6) }.

• This plugin version (git rev-parse --short HEAD): I did not check out git.
• This plugin's binary version (bin/languageclient --version): I don't have that binary
• Language server link and version: RLS installed according to https://rls.booyaa.wtf/install/

You can get the language client and server log.
See this.
If you show log, it will solve faster. :)

I also tried with :let g:LanguageClient_loggingLevel = 'DEBUG' but then I got nothing.

@Ploppz I think that is not LanguageClient-neovim issue but rls or rustc issue.

Ok, thanks
