I have been trying to sync a custom field created on ServiceNow end with a custom field on Azure end but with no luck. The name of the field is CR number(ServiceNow end ) and CR Number(Azure end) Below is the code I have using on both the side:


ServiceNow 

Outgoing:

replica.customFields."CR Number" = entity.customFields."CR number"

Incoming:

entity.customFields."CR number"?.value = replica.customFields."CR Number".value


Azure:

Outgoing:

replica.customFields."CR number" = workItem.customKeys."CR Number"

Incoming:

workItem.customKeys."CR Number"?.value = replica.customFields."CR number"?.value


Below is the error which I am getting:

com.exalate.api.exception.script.ScriptException: Cannot get property 'value' on null object at com.exalate.error.services.ScriptExceptionCategoryService.categorizeProcessorAndIssueTrackerExceptionsIntoScriptExceptions(ScriptExceptionCategoryService.scala:32) at com.exalate.processor.ExalateProcessor.executeProcessor(ExalateProcessor.java:47) at com.exalate.replication.services.processor.CreateIssueProcessor.$anonfun$executeScriptRules$1(CreateIssueProcessor.scala:103) at scala.util.Try$.apply(Try.scala:213) at com.exalate.replication.services.processor.CreateIssueProcessor.executeScriptRules(CreateIssueProcessor.scala:100) at com.exalate.replication.services.processor.CreateIssueProcessor.createIssue(CreateIssueProcessor.scala:77) at com.exalate.replication.services.replication.request.CreateIssueSyncRequestState.transition(CreateIssueSyncRequestState.scala:36)

      The serviceNow incoming in your incoming

      entity.customFields."CR number"?.value = replica.customFields."CR Number".value

      The error you encounter is

      Cannot get property 'value' on null object 

      Probably the 'replica.customFields."CR Number"' resolves to null, and the expression is not protected with the groovy safe navigation operator (the ?)
      You can inspect the content of the replica in the error details → remote replica

      If this shows to be true, find out why it is null
