Error synchronizing issues for application [Application Name]

Hello,

After an upgrade from BuildMaster 4.5.7 to 4.7.1, I receive the following error message every 20 minutes. Other applications are running fine. Any idea how to fix that issue?

Message: Error synchronizing issues for application Intranet: Object reference not set to an instance of an object

Stack:

I can see in Gibraltar the following issue reported:

Category: BuildMaster
Class Name: Inedo.BuildMaster.Windows.ServiceApplication.IssueTrackerSyncExecuter
Method Name: <Execute>b__0
Message: Error synchronizing issues for application Intranet: La référence d'objet n'est pas définie à une instance d'un objet.

Product: BuildMaster
Version: 4.7.1

This means that there is some error with your "Intranet" application's Issue Tracker configuration. It's likely that it was set-up partially, and before 4.7 the only way to see that was by attempting to view that application's issues. Now, you get an error message.

To resolve this, just go to that application's ISsue Tracker Settings and fix the configuration.

Thanks, it works fine now :)
