Conditional jsonpath expressions not working in groovy script, jmeter

Question

Conditional jsonpath expression: 
    $.[?(@.identifier == "369")]..columns.[?(@.type == "relationship")].token

• Problem 01: groovy script in jsr233 post processor not parsing the jsonpath expression.
• Problem 02: I need to loop identifier value in groovy or beanshell and fetch multiple array.

import groovy.json.JsonSlurper

JsonSlurper slurper = new JsonSlurper()
Map parsedJson = slurper.parseText(prev.getResponseDataAsString())

//String idval = parsedJson.sections[1].id

//String idval = parsedJson.[?(@.identifier == "369")]..columns.[?(@.type == "relationship")].token //trail 01 -failed at .[

String idval = parsedJson./[?(@.identifier == "369")]/..columns./[?(@.type == "relationship")]/.token  //trail 02 -no such property: columns for class

log.info(""+idval);

Answer 1

You cannot use JSON Path expressions with the JsonSlurper, consider either using find()/ findAll() functions on the returned collection or moving to JsonPath instead

def idval = com.jayway.jsonpath.JsonPath.read(prev.getResponseDataAsString(), '?($..sections[@.identifier == "369")]..columns.[?(@.type == "relationship")]')
