Hi All,

I'm migrating from BC14 to BC25, after publishing apps and while syncing the base application, getting an error as "Nullable object must have a value", and I'm unable to identify for which object I'm getting the error. When I check the event viewer, it's having the same error without any object details. Can someone help me how to find the object?

PowerShell error screen,

Below is the event viewer error,
