Dropdownbutton datasource does not accept map

[ericogan]

I am trying to use the following json as a datasource for a dropdown button. The original data is called FundsListQuery.

{
  "OGANICA EU": 6,
  "OGANICA USA": 3
}

I am trying to use {{ FundsListQuery.keys }}, but it says "value given is null".

Try formatting data like this: (I used a transformer as an example only)
