Bug SBP Exception during CalculateSceneDependencyData

Hello,

Recently we experienced build fails because of this error:

Build Task CalculateSceneDependencyData failed with exception:

Sequence contains no elements

  at System.Linq.Enumerable.First[TSource] (System.Collections.Generic.IEnumerable`1[T] source) [0x00010] in <7619ace64c6741ef82e9e455289b1377>:0 

  at UnityEditor.Build.Pipeline.Utilities.ExtensionMethods.FilterReferencedObjectIDs (UnityEditor.GUID asset, UnityEditor.Build.Content.ObjectIdentifier[] references, UnityEditor.BuildTarget target, UnityEditor.Build.Player.TypeDB typeDB, System.Collections.Generic.HashSet`1[T] dependencies) [0x000c9] in C:\Project\Library\PackageCache\com.unity.scriptablebuildpipeline@1.20.1\Editor\Utilities\ExtensionMethods.cs:104 

  at UnityEditor.Build.Pipeline.Tasks.CalculateSceneDependencyData.Run () [0x00370] in C:\Project\Library\PackageCache\com.unity.scriptablebuildpipeline@1.20.1\Editor\Tasks\CalculateSceneDependencyData.cs:169 

  at UnityEditor.Build.Pipeline.BuildTasksRunner.Run (System.Collections.Generic.IList`1[T] pipeline, UnityEditor.Build.Pipeline.Interfaces.IBuildContext context) [0x000cd] in C:\Project\Library\PackageCache\com.unity.scriptablebuildpipeline@1.20.1\Editor\Shared\BuildTasksRunner.cs:56 

The error is not consistent and happens most often in batchmode. The lack of information regarding the assets responsible for the exception make this tedious to debug. Any advice will be welcome.

Thanks

 

You can move sbp package from Library folder to Packages folder and add some logs to debug. For example, you can add a log in ExtensionMethods.FilterReferencedObjectIDs (Line 13 ~ 14) to see which asset causes this issue:

Code (CSharp):

1. public static ObjectIdentifier[] FilterReferencedObjectIDs(GUID asset, ObjectIdentifier[] references, BuildTarget target, TypeDB typeDB, HashSet<GUID> dependencies)
2. {
3.     // ...
4.  
5.     // We need to ensure that we have a reference to a visible representation so our runtime dependency appending process
6.     // can find something that can be appended, otherwise the necessary data will fail to load correctly in all cases. (EX: prefab A has reference to component on prefab B)
7.     foreach (var dependency in encounteredDependencies)
8.     {
9.         // For each dependency, add just the main representation as a reference
10.         var representations = ContentBuildInterface.GetPlayerAssetRepresentations(dependency.guid, target);
11.      
12.         ////---- BEGIN
13.         if (!representations.Any())
14.             Debug.LogErrorFormat("Error: {0}, {1}", asset, dependency.guid);
15.         ////---- END
16.      
17.         collectedImmediateReferences.Add(representations.First());
18.     }
19.     collectedImmediateReferences.UnionWith(encounteredDependencies);
20.     return collectedImmediateReferences.ToArray();
21. }

 

After adding a null-check and a 'continue' statement on it, it appears that the assets responsible for the exception to be thrown were 4 Sprites and the dependency was the SpriteAtlas from which those Sprites are comming from.

Both the SpriteAtlas and the Sprites are implicitly addressables because their parent folder is marked addressable.
The SpriteAtlas is referencing the same parent folder as content. Is this why the exception is thrown ?

No error concerning those Sprites was observed in build.

 

Which Unity version are you using? Since 'ContentBuildInterface.GetPlayerAssetRepresentations' is implemented in the Engine, maybe you can try a newer version to see if the issue still exists.
