Thank you! I got a validation error caused by an Item Granter Device that I created as part of the [Team Elimination Game](https://dev.epicgames.com/documentation/en-us/uefn/team-elimination-game-1-setting-up-the-level-in-verse) tutorial. The weapon granted by the device was the “ **Basic Sword L1** ”. This post helped me resolve the error by switching to a different weapon. ---

For anyone else experiencing validation errors please use this method to find the actors causing the issue: > [@UEFN Validation](https://forums.unrealengine.com/t/uefn-validation/835090/6): > > @InsanePete in your Output Log (different from message log) in the bottom left of UEFN you should see the same errors after running validation as you do in the message log. [image] Above those red errors you should see log lines pointing to .uasset files. If you copy just the names of the .uasset files (Exclude the .uasset part) and paste them into your outliner you should see which actors are causing the issue. Hope this helps! Thanks. ---

I have the same issue but with me these assets are the ones that make up my map, they are Blueprint Actors which house control rig and spot lights and are used for my light show. Which is made using sequencer. Any idea why it’s not liking these as to remove these removes my complete Idea for what I plan. ```plaintext LogValkyrieValidation: Display: Found disallowed objects /SecretAgent/Imported_SKL/GenericStageLights/Blueprints/Test_StageLight_Base.Test_StageLight_Base_C LogValkyrieValidation: Display: Found disallowed objects /Script/Engine.InheritableComponentHandler LogValkyrieValidation: Display: Found disallowed objects for asset Content/Imported_SKL/GenericStageLights/Blueprints/Test_StageLight_Base.uasset LogValkyrieValidation: Display: Found disallowed objects /Script/FortniteGame.UserOptionDefinitionStringMetaData LogValkyrieValidation: Display: Found disallowed objects for asset Content/Imported_SKL/GenericStageLights/Blueprints/Test_WashLight.uasset LogValkyrieValidation: Display: Found disallowed objects /SecretAgent/Imported_SKL/GenericStageLights/Blueprints/Test_StageLight_Base.Test_StageLight_Base_C LogValkyrieValidation: Display: Found disallowed objects /Script/Engine.InheritableComponentHandler ``` ---

Do you have an item granter that grants a melee weapon? Try to put in a range weapon and try again. ---

I believe this is a known issue with the Basic Sword being added to certain devices like the item remover at the moment. We’re working on a fix. Thanks! ---

I found a temp solution to this. Go in the outiliner and select the object incriminated, then details and then find the “disallowed property” in my case it was a material. Click on the “reset” arrow. You’ll notice that nothing will change because it’ll re-apply the same thing but… somehow it fixed it for me. ![solution](https://d3kjluh73b9h9o.cloudfront.net/original/4X/e/d/5/ed511406c9b2d9b97baa9b5c96941b3acdca98f4.png) ---

Thank you so much for this cool tip and explanation. I am also experiencing this bug so glad I now have a way to search for the actual actor in the Outliner that is causing the issue. For anyone else who needs an additional step to this advice, not all actors have names. If there is no name for your .uasset file, you can paste the numbers and characters after the / and before .uasset **Example** - here’s one of my errors `LogValkyrieValidation: Display: Found disallowed objects for asset Content/ __ExternalActors__ /Capture_The_Flag/8/XJ/O3IDILUT35VK4E6RI2V2T2.uasset` In this case you would just copy the O3IDILUT35VK4E6RI2V2T2 and paste this into the Outliner. Hope that helps! Looking forward to a fix for this bug soon but thanks again. ---

> what if the object doesnt even exist I get this a bit if I had it in a group at some stage (groups are broken rn). If a broken item was ever in the group - it will continue to throw the error (even after it was removed) until you delete the group (or actor that it was attached to). ---
