Reading from JSON app value

Hello everyone,

I am having troubles to read from a JSON format which is stored in my app variable.

When I try to list an item I am getting the variable name instead of the values:

Here is the setup:

And this is the JSON:

{ 'timestamp': DateTime.now().toString(), 'data': [ { 'description': 'Today Solar Energy', 'value': todayEnergySum[0].toString(), 'unit': 'kW', }, { 'description': 'Today Import Energy', 'value': todayEnergySum[1].toString(), 'unit': 'kW', } ] }

Any help is highly welcomed. Thank you.
