I have setup hybrid sync between 2 projects within a jira instance and get following error.

NullPointerException: Cannot set property ‘value’ on null object

Showing error in the script but does not point to which line

Below is the script,

OEM.issue.customFields.“OEM Affected Programs”.value = “Alexandra”  
[//OEM.issue.customFields](https://OEM.issue.customFields).“OEM Customer Severity”.value = “S2-Severe”

DAR.issue.customFields.“Platform Common”.value = “No”  
DAR.issue.customFields.“Translation Impacts”.value = “No”  
DAR.issue.customFields.“Affects PLQA Tests”.value = “No”  
DAR.issue.customFields.“Affected PLQA Tests are tested earlier”.value = “No”  
DAR.issue.customFields.“Triage Pattern”.value = “No”  
DAR.issue.customFields.“Is a Regression”.value = “Unknown”  
DAR.issue.customFields.“Recovery”.value = “Other”  
DAR.issue.customFields.“Feature”.value = “Other”

I have added script at the end of the field mapping.

One of the customfields don’t exist.  
To avoid the nullpointer, you can use the [groovy safe navigation operator](https://groovy-lang.org/operators.html#_safe_navigation_operator)  
DAR.issue.customFields.“Bogus”?.value will not result in a nullpointer (check the ?)

To locate the custom field - make sure that all fields exist
