👋 @ngosang, In order to help you further we'll need to see logs. You'll need to enable trace logging and replicate the problem that you encountered. Guidance on how to enable trace logging can be found in our troubleshooting guide.

Please post trace logs with a full stack-trace that shows the origin of the nullable movie instance.
