JSONPath does not return values when using in Karate but does using online evaluator

Question

I\'m fairly new to JSONPath so this could be my fault but when I try this expression in an online evaluator (https://jsonpath.com/) it works but does not in Karate.

Answer 1

The JsonPath engine is known to have issues with such complex expressions. Please use karate.filter() instead which I am sure you will agree is much more readable: https://github.com/intuit/karate#json-transforms

* def resources = $..resource
* def fun = function(x){ return x.resourceType == 'AllergyIntolerance' && x.category[0] == 'food' }
* def temp = karate.filter(resources, fun)
