[VIKAS MISHRA]

I Am trying to run below mentioned code in background script but in line no. 3 its showing me error "resp" is not defined.", please suggest how to resolve this.

responseBody = [{"isSuccess":false,"errorMessage":"Agreement: 00000288.0 is not present in Conga","apttus_contract_id":"00000288.0"},{"isSuccess":true,"errorMessage":"","apttus_contract_id":"00006475.0"}];
for(var i in responseBody){
        var flag = resp[i].isSuccess;
        if(!flag){
            resp[i].apttus_contract_id;
            gs.info('testing response For True/False');
        }
    }

Actually, go with what  AnirudhKumar suggests. 

I must be having a moment.

Add in a gs.info(responseBody[i].apttus_contract_id); to what he provided it looks good to me.

Try this:

responseBody = [{"isSuccess":false,"errorMessage":"Agreement: 00000288.0 is not present in Conga","apttus_contract_id":"00000288.0"},{"isSuccess":true,"errorMessage":"","apttus_contract_id":"00006475.0"}];
for(var i in responseBody){
        var flag = responseBody[i].isSuccess;
        if(!flag){
            responseBody[i].apttus_contract_id;
            gs.info('testing response For True/False');
        }
    }
