For example i have following payload to the APL doc.
"input": { "ARRAY1": [ { "ARRAY2": [ { }, { } ] }, ] }
I bound data to a container ${input.ARRAY1} and now inside that container i have another container where i bound data to ${data.ARRAY2}.
My question how can i access the length of ARRAY2. i tried ${data.length}. Which didnt work..
