Imagine you have a list where you then need to take a set portion of it as a batch.
Below gits shows how to use a while loop for this to creat batches.
By converting two lists into sets and then comparing them, we can get a list of items that weren't batch first time around. This works for a regular list.
However for a list of json objects, as above, we can't use set. If used as a regular list, it throws below error.
