What is the format for the payload parameter in the OpenAppWithPayload command?

Whenever I pass a URI/URL I receive an invalid parameters error:

❯ lgtv --name ankLG --ssl openAppWithPayload https://watch.plex.tv/show/airwolf/season/1/episode/1\?utm_source\=app.plex.tv\&utm_medium\=share
{"type": "error", "id": "0", "error": "2 invalid parameters", "payload": {}}
{"type": "error", "id": "0", "error": "2 invalid parameters", "payload": {}}
{"closing": {"code": 1000, "reason": ""}}
