Null reference when building player content

This is what I got after I try to build player content:

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object
2. UnityEditor.AddressableAssets.GenerateLocationListsTask.GetLoadPath (UnityEditor.AddressableAssets.AddressableAssetGroup group, System.String name) (at Library/PackageCache/com.unity.addressables@0.5.3-preview/Editor/Build/BuildPipelineTasks/GenerateLocationListsTask.cs:79)
3. UnityEditor.AddressableAssets.GenerateLocationListsTask.Run () (at Library/PackageCache/com.unity.addressables@0.5.3-preview/Editor/Build/BuildPipelineTasks/GenerateLocationListsTask.cs:66)
4. UnityEditor.Build.Pipeline.BuildTasksRunner.Run (System.Collections.Generic.IList`1[T] pipeline, UnityEditor.Build.Pipeline.Interfaces.IBuildContext context) (at Library/PackageCache/com.unity.scriptablebuildpipeline@1.2.1-preview/Editor/Shared/BuildTasksRunner.cs:50)
5. UnityEditor.GenericMenu:CatchMenu(Object, String[], Int32)

 

@Roni92pl I've seen this today and it happened because the "Built In Data" had no "BundledAssetGroupSchema" but the addressables tried to access it without testing for null. The only fix that worked for us was to add one (although that is not really the intention of the "Built in data" group).

 

@MNNoxMortem thanks!
