Grabbing .json response attribute value in output log & passing attribute values to propertiesstep

richie if custodian is subnode under meta then your code is correct.

If meta and custodians are separate nodes then all you have to do is - 

 def custodianval = object.custodian

One more thing to consider if those nodes are an array i.e., nodes are in [ ].

If so then you need to reffer that using a counter.

for ex:

object = {meta: [], custodian: [{name:test1, id:1}, {name:test2, id:2}] }

def cutodianval = object.cutodian[0] .name  would give you test1

hope this helps.
