JsonSyntaxException on startup about kotlin-language-server HOT 7 OPEN

I had the same JSON-related error when first trying this language server with neovim on Windows, and after a little debugging found that setting the init_options.storagePath property to a valid directory fixed it.

init_options = {
    storagePath = util.path.join(vim.env.XDG_DATA_HOME, "nvim-data"),
},

'util' is require('lspconfig/util'), and the environment variable plus the 'nvim-data' segment references a location on my machine. After starting the language server in neovim, I can see that the file kls_database.db is created there and the fatal error is gone.

Using the default init_options by omitting this property from my lua configuration did not help.

@SrDum using the default config for init_options solves this for me, previously I was using init_options = {}

edit: linux machine + neovim 10 nightly

The SLF4J warning is fine (maybe not fine, but expected 😄).

A delegate object is null, jsonrpc methods of 'public default org.eclipse.lsp4j.services.NotebookDocumentService org.eclipse.lsp4j.services.LanguageServer.getNotebookDocumentService()' are ignored

This is interesting. We don't provide this method, but the client shouldn't call it either since we don't advertise it in the server capabilities.

Internal error: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at path $

The JSON error confuses me. I'd wager a guess and say that it's generally some misconfiguration on the client-side.

I don't doubt it. How would I go about troubleshooting this?

Consult with the docs/maintainers of the language client you're using or try another client and see if the issues persist.

Alright, thank you.

I'm getting some sort of JSON error too on a fresh install, I haven't been able to find out what's going on:
