I’ve been referring to this documentation to update a custom Date Field between my 2 jira servers.

However I can’t seem to sync the date as whenever I try to exalate the issue, it doesn’t get updated on the opposing side.

I’m currently using this for incoming sync for both sides:  
replica.customFields.“Contract Start Date” = issue.customFields.“Contract Start Date”

and outgoing sync for both sides:  
issue.customFields.“Contract Start Date”.value = replica.customFields.“Contract Start Date”.value

Would I still need to change the date processor as its between 2 jira servers. I’ve linked the documentation below.

heyAdam Chin . You have a null pointer exception on row 29 in your script. We had a similar discussion here: [Cannot get property ‘value’ on null object](https://oldcommunity.exalate.com/questions/11338428/cannot-get-property-value-on-null-object)_(old community)_ . Can you if there is a value in that custom field and f the names or id’s of these fields are entered correctly
