def object = jsonSlurper.parseText(’’’{ “status”:1, “message”:“success”, “result”:{ “id”:“2kxv1dvtovf-ab23ad18-cffe-46d4-bf83-4bb380560dea”,“token”:“2w2c6ql8849-32fb9336-7995-47c4-9024-6a35c6043621”,“country_code”:“91”,“mobile_number”:“9091401966”, “first_name":“Dipak”,“last_name”:“Das”,“email”:"dipak.das@gmail.com”,“status”:0 },“success”:true, “hasError”:false}’’’)
println("\n")
println(object) //// its run fine and shows whole object
println(object.token) ///--------------- then token is not recognizable and not show the token

		 } }

System.out.println(response.getResponseText())
WS.verifyResponseStatusCode(response, 200)
//assertThat(response.getStatusCode()).isEqualTo(200)
WS.verifyElementPropertyValue(response,‘result.id’,‘2kxv1dvtovf-ab23ad18-cffe-46d4-bf83-4bb380560dea’)
WS.verifyElementPropertyValue(response,‘result.country_code’,‘91’)
WS.verifyElementPropertyValue(response,‘result.mobile_number’,‘9091401966’)

2nd issues I face when I run the test case in console view I get this error message and then result of test case execute:

SLF4J: The requested version 1.7.16 by your slf4j binding is not compatible with [1.6]
SLF4J: See SLF4J Error Codes for further details.

So I am having doubt that my test case is running successfully or not.
Please help urgently.
