Filters and inline dateDiff function not working

Hi There.

I’m trying to use a dateDiff function in a filter to calculate the hours difference between now and timestamp which is an element from a json parser.

From the right side filter of an iterator module:

Condition:
dateDiff(now; parseDate(TIMESTAMP; “YYYY-MM-DDTHH:mm:ss”); hours)

Numerical Less than
4

I use a text aggregator and filter inspector to see what’s happening. It’s almost like inline functions do not work.
