I'm getting similar errors using this language server for javascript

https://github.com/theia-ide/typescript-language-server

That exact error appears and then some others depending the codeaction

Try Coc.nvim with typescript.

[LC] Error: Failure { jsonrpc: Some(V2), error: Error { code: MethodNotFound, message: "Unhandled method textDocument/completion", data: None }, id: Num(3) }

I think you should post log file defined by let g:LanguageClient_loggingFile = '/tmp/lc.log', so that we could inspect the lsp traffic to prove that this is LanguageClient-neovim issue or haxe-language-server issue.

[vushu]

The haxe-language-server listens to a didChangeConfiguration event at start and needs some initializationOptions
