JSON Api

Hi, I am in trouble trying to use the JSON Api.

I am sending
_{curl -X POST --http0.9 -d '{"jsonrpc": "2.0", "params": {"command": "serverinfo", "tan": 1}}' <hyperion_ip>:19444}

But I get

_{{"command":"","error":"Errors during message parsing, please consult the Hyperion Log.","success":false,"tan":0}}

And the logs shows "Failed to parse json data from JsonRpc / Illegal value"

_{2022-07-21T12:48:19.117Z [JSONSERVER] (DEBUG) (JsonServer.cpp:101:newConnection()) New connection from: ::ffff:<client_ip>

Any thoughts ?

Thanks a lot Pclin.

I am now able to use the API.

I thought hyperion was using JSON-RPC "standard" (as stated at https://www.jsonrpc.org/).
