Mapper to retrieve field value with null check
I have to extract "pw_cc__IsoCode_2__c" when in the payload "Country_of_Installation__r" is present.
Since both parent property Opportunity and child property Country_of_Installation__r are optional field i need to check if the node present before extracting the value. I tried in mapper $.get('Opportunity').get('Country_of_Installation__r').get('pw_cc__IsoCode_2__c') but this throws can not invoke a method on null value.
Tried other javascript functions but most of them are not supported here.
can anyone help me with proper script.
[{
"OpportunityId":"0063x00001bZVt8AAG",
"Opportunity":
{
"Id":"0063x00001bZVt8AAG",
"Country_of_Installation__r":
{
"attributes":
{
"type":"aaaaaa",
"url":"/services/data/v60.0/bbbb"
},
"Id":"a4u120000008XpbAAE",
"pw_cc__IsoCode_2__c":"MZ"
}
}
}]
