I am currently trying to set up the connections for our Sync between Jira and DevOps, but I am having a few errors come up that I am unsure of the solution. Please find below the error:

java.base/java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:183)
Caused by: java.lang.NumberFormatException: Character array is missing "e" notation exponential mark.

As per previous recommendations, this new snippet has been tried

Current:

workItem.customKeys."Tester"  = replica.assignee

Expected:

workItem.customKeys."Tester"?.value  = replica.assignee.value

After try, this seems to have stopped to error, but it is not populating the Tester field within DevOps. It is possible to sync a user field (other than Assignee) in DevOps with Exalate?
