Hello there. As I want to move my Project to the atmoky spatializer plugin i need to upgrade to the FMOD 2.02.29 Implementation. I am running Unity 2020.3.48. Unfortunately I am stuck at the “Update Event References” section. After scanning for [EventRef] with the updater it finds 77 [!] tasks and after hitting Execute it stops updating after TWO scripts! I get the following error message: NullReferenceException: Object reference not set to an instance of an object FMODUnity.EventReferenceUpdater.ExecuteGameObjectTask (FMODUnity.EventReferenceUpdater+Task task, FMODUnity.EventReferenceUpdater+SavePolicy savePolicy) (at Assets/Plugins/FMOD/src/Editor/EventReferenceUpdater.cs:1663) FMODUnity.EventReferenceUpdater.ExecuteTask (FMODUnity.EventReferenceUpdater+Task task, FMODUnity.EventReferenceUpdater+SavePolicy savePolicy) (at Assets/Plugins/FMOD/src/Editor/EventReferenceUpdater.cs:1623) FMODUnity.EventReferenceUpdater+d\_\_46.MoveNext () (at Assets/Plugins/FMOD/src/Editor/EventReferenceUpdater.cs:755) FMODUnity.EventReferenceUpdater.UpdateProcessing () (at Assets/Plugins/FMOD/src/Editor/EventReferenceUpdater.cs:1797) UnityEditor.EditorApplication.Internal\_CallUpdateFunctions () (at \<25578071f6e44201aac745680e5c8dfc\>:0) Am I supposed to change all [EventRef] manually!? ---

Yes you will need to manually change all the [EventRef] yourself, the Updater will assist in locating all references.

That is all “nice ”and good but how (why) do I update scripts that are provided by the FMOD Update? There’s no way of me changing that! I understand that my scripts have to be changed but how do I do that with a FMOD Studio Event Emitter? ![Screenshot 2025-08-27 175409](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/a/a21f08d3d61982986bf367a1c122ad22ca73ad01.png) ---

Thanks for clarifying that this is occurring with the StudioEventEmitter script, that step should be handled by the Event Reference updater but it appears to be stopped by the `NullReferenceException` you mentioned. Are you able to share your entire editor log file? You can locate this from the editor console window ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/d/d4a0612155d940c4cfc08a5a636a345c87948c66.png) ---

Sorry for coming back to you that late, I managed to change everything but man, the process was a nightmare! I hope the new updates for FMOD will not be breaking ones like this one. The Updater always stopped because of some broken prefabs…so once I updated/deleted them the updater worked as expected. ---

We have some bigger fixes planned for the Reference Updater but I’m unable to give any sort of time frame on them at this point. ---
