How to check Mapping field not have any value

[stephenb (Stephen Brown)]

Hi @PappuSingh

Please format your code in the future ... you have to check if the field exists you can not get the .value on a field that does not exist

I thought we answered this here

Subtraction between current date and doc created date

Do you want Days in Integer or Float? Field Type Double long datenow = new Date().getTime(); long datewas = doc['@timestamp'].value.getMillis(); double days = (datenow - datewas) / 86400000.0; emit (days); Field Type Long long datenow = new Date().getTime(); long datewas = doc['@timestamp'].value.getMillis(); long days = (datenow - datewas) / 86400000; emit (days);

If you just want to check do something like this

if(doc['readyCreatedTime'].empty) {
  emit(0);
  return;
}

long datenow = new Date().getTime();
long datewas = doc['readyCreatedTime'].value.getMillis();
long days = (datenow - datewas) / 86400000;
emit (days);
