Reuse an existing config/remove duplicates when importing multiple examples. Merge the README sensorToNodeRed and forwardedToHub routes into edgeHub.properties.desired.routes, replacing sensor/nodeRed with actual deployment module IDs. The sensor module must emit JSON on output1. Inspect the received body, then verify upstream output2: object payloads gain forwardedAt; arrays/scalars retain their values. The Function re-encodes literal strings as JSON text because Module Output parses string payloads as JSON. Complete is SDK send completion, not downstream processing.
