Error: No locations found

[mrphil2105]

When using any of the functions provided I get the error "No locations found". OmniSharp is installed via Mason and is working fine if not called through omnisharp_extended. Any idea what might be causing this?

Hello, Have you provided correct path to OmniSharp when configuring LSP? It'd be great if you could provide:

1. Output of :LspInfo
2. Enable LSP debug logging via vim.lsp.set_log_level("DEBUG") and provide the output of :LspLog after you tried using one of the commands

OmniSharp is only installed through Mason and I do not set it up in any specific way in my LSP config other than doing the following:

require("mason-lspconfig").setup_handlers {
    function(server_name)
        require("lspconfig")[server_name].setup {
            capabilities = capabilities,
            on_attach = on_attach,
            settings = servers[server_name],
            filetypes = (servers[server_name] or {}).filetypes,
        }
    end,
}

Hmm, looks fine more or less. On what symbol are you trying to invoke go to definition?

[Hoffs]

Okay, managed to replicate it, the fact that your directory "CSharp Projects" contains spaces causes the issue. Seems like omnisharp does not like that it gets url encoded (space -> %20), will see what's the deal here.

Merged an update that should resolve this issue, in my testing it works well on both Windows and Unix when directories have spaces (it should also handle other URI encoding thingies).

If you still have issues, feel free to reopen this issue.
