Script is not working, throwing an error

Hi Team,

I have implemented a script for calculating Number Of Weeks:

import com.atlassian.jira.component.ComponentAccessor


def dateFieldObject = ComponentAccessor.customFieldManager.getCustomFieldObjectsByName("Start Date")[0]

def dateFieldObject2 = ComponentAccessor.customFieldManager.getCustomFieldObjectsByName("End Date")[0]


def dateValue= issue.getCustomFieldValue(dateFieldObject) as Date

def dateValue2= issue.getCustomFieldValue(dateFieldObject2) as Date

def now = new Date()


def diffdate


// if "End Date" is reached or exceeded, which means "now" is later than "End Date"

if (now.after(dateValue2)){

    // End Date - Start Date

    diffdate = dateValue2 - dateValue

} else {  // if now is before or equal to "End Date"

    // End Date - now

                diffdate = dateValue2 - now



if (diffdate) {

    double noofweeks = diffdate/7

    double roundNoOfWeeks = Math.round(noofweeks)

    int value = (int) roundNoOfWeeks;

                return value



but getting attached error, please kindly check and give me some solution where I am doing error.PNGwrong.

The error message says line 6 is failing.  I think the code on that line is the one trying to get a date from the "start date" field.  A null pointer error here means that there is no data in something you are passing into a method on that line.

Either the field does not exist for this issue, or the data in it is not a date, or is empty.
