<![CDATA[Accessing decoded JSON array]]>Hello,
I am new to using UIFlow, but not to programming.
I am using UIFlow on my M5Stack project.
I am having difficuly in accessing a JSON decoded array.
Within the Python code I have a snippet of code:-

Decoded_Packet = json.loads(Packet)
Decoded_Location = Decoded_Packet["location"]

Which works in my application, but it won't change to the UIFlow - Blockly representation, nor save and load correctly.
So my question in Blockly what is the equivalent of:-
Decoded_Location = Decoded_Packet["location"]
or
Decoded_OutTemp = Decoded_Packet["stats]["current"]["outTemp"]

Which work in the Python coding.

Regards
Phil.

I'm subscribing to an AWS IOT topic which is publishing a JSON. I can receive the whole message but in trying to extract one field from the JSON its not returning anything. Pic below

Get key location from map Decoded_Packet
