Use custom definition for a pre-defined languageID (YAML)

[GSri30]

So I am trying to use yaml as LanguageID. I can see (from monaco.languages.getLanguages()) that there are some pre-defined languages that are already loaded into monaco. This list also contains yaml.

Now I have my DSL built upon yaml (I have specific keys and values domain). When I'm trying to integrate my react app with my language server, I'm not getting few functionalities (eg. textDocument/completion). I logged the messages on the server and I wasn't getting textDocument/completion method being triggered from client side (Though few other methods like textDocument/didChange, textDocument/publishDiagnostics, textDocument/foldingRange) were getting triggered.

What could be the fix.

Does the language server declare the capability ?

[GSri30]

Yeah. It does declare the capability. If I try to use the same language server and language client with different languageID config, its working. Its just that, with yaml as LanguageID, its not.

Can you provide a minimal repo reproducing the issue?
