91103: Event type list is empty

This error occurs when you create or update an Event Streams subscription without providing any event types in the Types list. Event Streams subscriptions require a set of event type and schema version pairs, and the Subscription resource requires the types request parameter.

• Your request to the Subscription resource included an empty Types array.
• Your application built the subscription payload without adding any event type entries before sending the request.

• Add at least one event type to the Types parameter when you create the subscription. Each entry should identify an existing event type and can include a schema_version.
• Verify the event types you want to subscribe to before sending the request. Use the Event Type resource to review available event types and schemas.
• If you manage event types after creating the subscription, use the Subscribed Event resource to add event types to the subscription instead of submitting an empty list.
