I'm trying to send an EventInput using python dialogflow client v2 (https://dialogflow.com/docs/reference/api-v2/rest/v2beta1/projects.agent.sessions/detectIntent#eventinput) but couldn't set parameters.
Setting it to an object like
{"result_guid": "49A8608C-4854-4964-81C3-0A75F912B994"}
returns an error ValueError: Protocol message Struct has no "result_guid" field.
How can this be solved?
