Hi everyone, I'm having errors in console linked to the first implementation of Timeline signals in my project. Architecture I have two scenes (Main Menu and First Level). From Main Menu, you can go to First Level by clicking on a button. The Signal receiver script is on a component in First Level scene. So is my Timeline with the signals markers. But when launching Main Menu scene, I have the following errors three times even though, I can fully play the game with no problem. I was just wondering if this comes from my architecture, ex : should I have my Signal Receiver in Main Menu instead? Or may I ignore this error ? Code (CSharp): SerializedObjectNotCreatableException: Object at index 0 is null UnityEditor.Editor.CreateSerializedObject () (at <3e481e8f36eb4d4c8d94b9ba6b2be438>:0) UnityEditor.Editor.GetSerializedObjectInternal () (at <3e481e8f36eb4d4c8d94b9ba6b2be438>:0) UnityEditor.Editor.get_serializedObject () (at <3e481e8f36eb4d4c8d94b9ba6b2be438>:0) UnityEditor.Timeline.Signals.SignalReceiverInspector.OnEnable () (at Library/PackageCachefirstname.lastname@example.org/Editor/Signals/SignalReceiverInspector.cs:26) Thanks for your help!
