I try to create an app with Add-on Builder, with the purpose to get records from JSON array.
As most of the records were created with the same timestamp and taking into account that there are thousands of records (so I have to make it partially), I try to use the startIndex=0 as initial record for a checkpoint with step (pageSize)=100.
What I'm expecting is with the next call it will move the checkpoint to an array record 99 and pull the other 100 and so on.
Here's the configuration:
JSON path=$.recordID (not an order-based value, just to use for breaking the data into individual events)
Checkpoint parameter name = start
Checkpoint field path = 
Checkpoint initial value = 0
Test passed with no errors and returns records from array, but after saving - nothing is indexed.
What is wrong with this setup?
