如何从Golang中的Dialoflow Webhook踢FollowupEvent

I am not familiar with Go. Could you tell me how to build correct structure of dialogflow.GoogleCloudDialogflowV2WebhookResponse for Followup event.

The following code is not working:

return dialogflow.GoogleCloudDialogflowV2WebhookResponse{
    FollowupEventInput: &dialogflow.GoogleCloudDialogflowV2EventInput{Name: "event-follow"},
}

solved:

foovar:= &dialogflow.GoogleCloudDialogflowV2EventInput{ LanguageCode: "en", Name: "nextevent-follow", Parameters: []byte(messages), }
