I was able to get the source from binary file and convert into JSON (as image below, it’s merged and ready to be the input “Data” to to be my http request JSON body)
Kindly refer to my screenshot
#1 - An ARRAY of objects called “Data” is now act as my locations object
#2 - It’s successfully transfer to http request node as input, can see Data array is available with 2 location obj
#3 - safely use the markup {{ $json.Data }} and it’s resolved as 2 objects (marked as #4 in screenshot)
But i noticed an error soon, there is a missing array to encapsulate the two locations. Kindly advise what could be the possibly wrong? thanks
