i am following the guideline posted at  
[https://docs.katalon.com/katalon-studio/docs/parse\_json\_responses.html#get-a-key-value](https://docs.katalon.com/katalon-studio/docs/parse_json_responses.html#get-a-key-value)

but test case failed during execution  
Reason:  
groovy.lang.MissingPropertyException: No such property: parsedJson for class: Script1567646760099

2019-09-05 09:34:27.003 INFO c.k.katalon.core.main.TestCaseExecutor - END Test Cases/json

================  
i have groovy as follow, i paste the expected response in the script. basically the response is identical to request.

import groovy.json.JsonSlurper

String jsonString = ‘’‘{  
“itemId”: “test123”,  
“codes”: [  
{  
“code”: “C1”,  
}  
],  
“name”: “item one”,  
“status”: “active”,  
“created”: “2019-09-04T05:47:30.944Z”,  
“itemType”: “A1”  
}’‘’  
JsonSlurper slurper = new JsonSlurper()  
Map parsedJson = slurper.parseText(jsonString)

=======  
then the test case part 2 to verify response, after part 1 sent the request successfully. part 1 had been sent successfully in this case, the problematic area is the part 2 verify json response.

Let me assume that the following is a entire test case script you wrote (from the very 1st line to the very last line).

```auto
import static com.kms.katalon.core.checkpoint.CheckpointFactory.findCheckpoint
import static com.kms.katalon.core.testcase.TestCaseFactory.findTestCase
import static com.kms.katalon.core.testdata.TestDataFactory.findTestData
import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject
import com.kms.katalon.core.checkpoint.Checkpoint as Checkpoint
import com.kms.katalon.core.cucumber.keyword.CucumberBuiltinKeywords as CucumberKW
import com.kms.katalon.core.mobile.keyword.MobileBuiltInKeywords as Mobile
import com.kms.katalon.core.model.FailureHandling as FailureHandling
import com.kms.katalon.core.testcase.TestCase as TestCase
import com.kms.katalon.core.testdata.TestData as TestData
import com.kms.katalon.core.testobject.TestObject as TestObject
import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI
import internal.GlobalVariable as GlobalVariable

import com.kms.katalon.core.util.KeywordUtil

import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject
import com.kms.katalon.core.configuration.RunConfiguration
import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS
import static org.assertj.core.api.Assertions.*

//part 1. send the POST message
WS.sendRequest(findTestObject('Drug Service/DS-post-drugformulary'))

result = CustomKeywords.'json.API.AddDrug'()
print(result)

//part 2. to check the json response
String getSelectedKey = parsedJson.itemId.name

if(getSelectedKey == null) {
    KeywordUtil.markFailed("Key is not present")
}

if (!isKeyPresent) {
    KeywordUtil.markFailed("Key is not present")
}

```

In this framgment, the variable named `parsedJson` IS NOT defined at all. Therefore surely you will encounter a error with message “groovy.lang.MissingPropertyException: No such property: parsedJson for class: …”

i thought it is in the groovy file, not?  
import groovy.json.JsonSlurper

String jsonString = ‘’’{  
“itemId”: “test123”,  
“codes”: [  
{  
“code”: “C1”,  
}  
],  
“name”: “item one”,  
“status”: “active”,  
“created”: “2019-09-04T05:47:30.944Z”,  
“itemType”: “A1”  
}’’’  
JsonSlurper slurper = new JsonSlurper()  
Map parsedJson = slurper.parseText(jsonString)

yes 2 groovy, as i separated 1 groovy for test case part 1, another groovy for test case part 2. the groovy content i posted is for part 2 only.

what is not clear?  
let me know which one you needed.  
i have posted the groovy and test case. part 1 has no issue, please do not look at it, thus groovy for part 1 i would not posting here.
