These are the 3 nodes:
[{"id":"a2b9b7d51d629336","type":"mqtt in","z":"d65ab744.465758","name":"","topic":"ARLEC-1/#","qos":"2","datatype":"auto","broker":"378c0403.8cda04","nl":false,"rap":true,"rh":0,"inputs":0,"x":810,"y":420,"wires":[["e526db181bab789a","28868a5dfe0ca601"]]},{"id":"e526db181bab789a","type":"json","z":"d65ab744.465758","name":"","property":"payload","action":"","pretty":false,"x":990,"y":420,"wires":[["abec26cc161f6cbd"]]},{"id":"28868a5dfe0ca601","type":"debug","z":"d65ab744.465758","name":"RAW ARLEC-1 message","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":1050,"y":470,"wires":[]},{"id":"378c0403.8cda04","type":"mqtt-broker","name":"TIMEPI MQTT","broker":"192.168.0.99","port":"1883","clientid":"","usetls":false,"compatmode":false,"keepalive":"60","cleansession":true,"birthTopic":"","birthQos":"0","birthRetain":"true","birthPayload":"","closeTopic":"","closeQos":"0","closePayload":"","willTopic":"","willQos":"0","willPayload":""}]
This is what I see as the RAW message:
{"topic":"ARLEC-1/tele/LWT","payload":"Online","qos":0,"retain":false,"_msgid":"94f63726e95a2b79"}
and I am seeing this error from the JSON
node:
Unexpected end of JSON input
Now, I know I have the JSON
node set to autodetect.
I fear I have messed up in the message structure, but can't be sure.
