Answer

The context.protocols object is only included in event payloads when a tracking plan is attached to the source. If a source does not have a tracking plan, event blocking is managed by schema filters, and the context.protocols object will not be present in the event payloads. To include the context.protocols object, attach or enable a tracking plan for the relevant source.
