For starters,
Appreciate the handy toolbox item - payload tester in debug panel:
So wondering how it’s best to process / render data in regards to json;
taking an example workflow here,
I gather:
*MQTT node puts data in a string
*json decode node separates that into objects
*Endpoint reply returns that back, curiously is re-encoding as json (string?) required?
With that, as you see in the toolbox above, doesn’t like to parse with template helpers. Noting replyData is an array of objects, like [0: {“Name”: “Smith”, “Date”:“5/17/23”}]
(But there are no commas separating any items in the debug panel, even beyond the replyData)
And to be sure for 3rd step above, removing jsonEncode doesn’t work as the debug panel shows ‘not able to render json’ (workflow times out) -
