Apex Specialist Superbadge - Null Product Life Span Months
Requirement: Another aspect about parts is they all have different lifespans. Therefore, you need to calculate and set the next service due date to the end of the maintenance cycle defined on the related equipment record.
Relevant Code:
The system debug confirms that it finds matching Product codes, but shows both prodExpiration and prod.lifespan_months__c as being null. Should the direct field reference show up at a minimum? And is there a better way to go about this?
Relevant Code:
Public Static List<Product2> prodCodes = [SELECT Id, productCode, lifespan_months__c FROM Product2];
Public Static Decimal prodExpiration;
for(Product2 prod : prodCodes){
if(newCase.Product__c == prod.productCode){
system.debug(newCase.Product__c);
system.debug(prod.productCode);
prodExpiration = prod.lifespan_Months__c;
system.debug(prodExpiration);
system.debug(prod.Lifespan_Months__c);
}
}
//This line is throwing a null pointer error according to salesforce
Decimal daysTilDue = prodExpiration * 30;
Date_Due__c = date.today()+ daysTilDue.intValue(),

When assigning the variable, you should check for null and assign zero if that is your default value, e.g.:
