Only Symbols works, All other commands gives no response

[mtangoo]

I have this problem that I have no idea what am doing wrong. I have this editor (closed source) that works fine with Serenata, but only symbols (textDocument/documentSymbol) works with this LS. If anyone can figure out what am doing wrong, I will be grateful. Hover for example, does not work

here is the hover command which works with Serenata but not with this Lang Server

{
    "id": 7,
    "jsonrpc": "2.0",
    "method": "textDocument/hover",
    "params": {
        "textDocument": {
            "uri": "file:///Users/hosanna/Projects/ProjectFolder/Controller.php"
        },
        "position": {
            "line": 568,
            "character": 26
        }
    }
}

Here is my initialize JSON-RPC.
