When i try to book a appointment on Vapi to create event google calendar module it has a error and says Validation failed for 2 parameter(s). Missing value of required parameter 'start'. Missing value of required parameter 'email'. Automatic failure response was sent to the webhook. My scenario looks like this below Vapi Webhook > create event (Google calendar) > webhook Does anyone know how to fix this? Is this a problem in the vapi side or the make scenario in the google calendar module?
