JMeter Dynamic JSON list generation - json

Question

i'm using the following groovy script :
def oldRequest = new groovy.json.JsonSlurper().parseText(sampler.getArguments().getArgument(0).getValue())
oldRequest.values().removeAll{it.equals('null')}
oldRequest.advancedFilters.values().removeAll{it.equals('null')}
def newRequest = new groovy.json.JsonOutput().toJson(oldRequest)
sampler.getArguments().removeAllArguments()
sampler.setPostBodyRaw(true)
sampler.addNonEncodedArgument('',new groovy.json.JsonOutput().prettyPrint(newRequest),'')
to remove Keys from JSON request where the values are "Null", i also want to include logic to convert below JSON:
{
"sortOrder": "A",
"sortField": "policyNumber",
"searchTerritories": [ter1|ter2|ter3],
"pageNumberRequested": "1",
"pageCountRequested": "50",
"policyStatus" : "${ActionStatus}",
"includeTerm : "null",
"advancedFilters": {
"test" : "null",
"test1" : [A|B],
"test1" : [C|D|E]}
}
to:
{
"sortOrder": "A",
"sortField": "policyNumber",
"searchTerritories": ["ter1","ter2","ter3"],
"pageNumberRequested": "1",
"pageCountRequested": "50",
"policyStatus" : "${ActionStatus}",
"advancedFilters": {
"test1" : ["A","B"],
"test2" : ["C","D","E"]}
}
I want the input JSON values to be converted from [ter1|ter2|ter3] to ["ter1","ter2","ter3"] and [A|B] [C|D|E] converted to ["A","B"] ["C","D","E"], please help me with the groovy script modifications required.

Your source data is not a valid JSON, you can check it using i.e. online JSON validation tool
Therefore unfortunately you will not be able to use JsonSlurper, you will have to treat the source data as normal text and amend it according to your needs using i.e. Regular Expressions
Example code:
def oldRequest = sampler.getArguments().getArgument(0).getValue()
log.info('Before: ' + oldRequest)
oldRequest = oldRequest.replaceAll('(\\w+)\\|', '"$1",').replaceAll('(\\w+)\\]', '"$1"]').replaceAll("(?m)^.*null.*(?:\\r?\\n)?","")
def matcher = (oldRequest =~ /test\d+/)
def i = 0
while (matcher.find()) {
oldRequest = oldRequest.replaceFirst(matcher.group(0), 'test' + ++i)
}
log.info('After: ' + oldRequest)
sampler.getArguments().removeAllArguments()
sampler.addNonEncodedArgument('', oldRequest, '')
sampler.setPostBodyRaw(true)
