Uncertainty about WebRTC Error definition

[helu-milestone]

In the WebRTC specification the following is written about an error:

This message is a [JSON-RPC] "Request notification" and shall include [JSON-RPC] "Error object" in its params field.

According to JSON-RPC specification (https://www.jsonrpc.org/specification), an "Error object" should contain an error member with the same members as defined by in ONVIF WebRTC. But does that mean that the Error should look like this:

{"jsonrpc": "2.0", "params": {"error": {"code": -32700, "message": "Parse error"}}} or simply
{"jsonrpc": "2.0", "params": {"code": -32700, "message": "Parse error"}}

Or is the ONVIF specification a bit of when talking about the params field in an error? Should the error object follow the JSON-RPC describtion of an Error(without id), as the ONVIF Spec writes that it shuld be a notification:

{"jsonrpc": "2.0", "error": {"code": -32700, "message": "Parse error"}}
