Hi, can anybody explain me how to transfert the right datas from a 1st function node to a second function node? I can't make it. The result is always: "{"error":{"code":400,"message":"Parse Error","errors":[{"domain":"global","message":"Parse Error","reason":"parseError"}]}}" Here are the nodes: …

Your second function node { "considerIp": "false", "wifiAccessPoints": [ { "ssid": "msg.payload.flag.baseElements[0]", "macAddress": "msg.payload.flag.baseElements[1]", "signalStrength": "msg.payload.flag.baseElements[2]" } ] }; You shouldn't have the quotes around…

Thanks ukmoose, unfortunatly... still have this message after correcting : function : (error) "TypeError: Cannot read property '0' of undefined" It is like I can get the good datas from the 1st node...

As this document is nearly Chinese for me and get more than hundreed lines with different directions and purpose, it does not help me more and it does not explain what to import in the second function node... You could also tell me the solution is under my eyes ... …

Hi @jycemea the bit of the documentation that is specifically relevant to your question is this section: https://nodered.org/docs/user-guide/messages#understanding-the-structure-of-a-message In particular, it describes the three buttons that appear when you hover over any message element - one of …

Thanks knolleary for this precision... I did it without any better result as below : var data = { "considerIp": "false", "wifiAccessPoints": [ { "ssid": payload.wifiAccessPoints[0].ssid, "macAddress": payload.wifiAccessPoints[0].macAddress, "signalStrength": payload.wifiAccessPoints[0].signa…

[image] jycemea: payload.wifiAccessPoints[0].ssid should be msg.payload.wifiAccessPoints[0].ssid

[image] hotNipi: msg. Nice!!! Did it...but errors with answer cause I used test datas. I'm going to try with real ones! Thanks!!!
