Hello Mario,
You need to place the following script in your connection:
Outgoing Sync Jira Cloud 1
replica.customFields."Bug" = issue.customFields."Bug"
Incoming Sync Of Jira Cloud 2
if(replica.customFields."Bug".value?.value == ["Yes"]){
issue.customFields."Bug Fix Approved (Team Leaders)".value = ["Yes"]
issue.customFields."Bug fix reason"?.value = "NAVMOBILE"
}else{
issue.customFields."Bug Fix Approved (Team Leaders)".value = []
issue.customFields."Bug fix reason".value = null
}
The problem is that this check box may be checked after the task is created so it errors for a null object
Hello 
I am sending a picture of the exact field. It is the same on both sides
Hi
It depends on what type of fields you use for the option "yes". Is it a text field, list, or any other type.
Do you use Cloud or DC?
I would by with looking at this documentation:
https://docs.exalate.com/docs/how-to-synchronize-custom-fields-in-jira-cloud
This is for on-prem:
