Cannot decode UTexture2D

[TheNaeem]

Hello, I'm trying to export a texture icon as UTexture2D, and when calling Decode() it throws this exception:
System.ArgumentNullException: Value cannot be null. (Parameter 'source') at System.Linq.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument) at System.Linq.Enumerable.TryGetFirst[TSource](IEnumerable 1 source, Func 2 predicate, Boolean& found) at System.Linq.Enumerable.FirstOrDefault[TSource](IEnumerable 1 source, Func 2 predicate)

The exception is thrown at line 113 of UTexture2D.cs

And this is how I'm loading the texture:

var texture = provider.LoadObject(@"FortniteGame/Content/UI/Foundation/Textures/Icons/Backpacks/T-Icon-Backpacks-773-Carabus-L");

var image = texture.Decode();

Thank you, I hope I was able to be descriptive on my issue, and hopefully it's just me doing something wrong.

what's the full code

error is fixed now but thank you anyways :)

The issue is happening again after verifying my game files, here is the full code:

var provider = new DefaultFileProvider(@"C:\Program Files\Epic Games\Fortnite\FortniteGame\Content\Paks", SearchOption.TopDirectoryOnly, true);
                provider.Initialize();

                var guid = new FGuid("00000000000000000000000000000000");
                var aes = new FAesKey("3FE5C589D219E71EE15FEB8FA9BC6B6224BB58AA826A0FA1D997D92E0D8DB23A");
                provider.SubmitKey(guid, aes);
                var texture = provider.LoadObject<UTexture2D>(@"/Game/UI/Foundation/Textures/Icons/Backpacks/T-Icon-Backpacks-773-Carabus-L"); //error throws on this line

provider.LoadMappings() after submitkey

[TheNaeem]

the exception still gets thrown

[4sval]

I just tested it and there's absolutely no issue if you do everything right
initialize the provider, submit keys, load mappings, load object

[TheNaeem]

Did I do everything correctly in the code I provided above? I'm really not sure what else there is to do. Is your working code different than mine?

[TheNaeem]

Also, you can't see it in the code snippet but as I mentioned earlier, the exception isn't thrown when the texture is loaded, it's thrown when I called the Decode method

[4sval]

because you have no mappings

[TheNaeem]

idk man, even with loading the mappings the exception still throws:

            var provider = new DefaultFileProvider(@"C:\Program Files\Epic Games\Fortnite\FortniteGame\Content\Paks", SearchOption.TopDirectoryOnly, true);
            provider.Initialize();
            provider.LoadMappings();

            var guid = new FGuid("00000000000000000000000000000000");
            var aes = new FAesKey("0x3FE5C589D219E71EE15FEB8FA9BC6B6224BB58AA826A0FA1D997D92E0D8DB23A");
            provider.SubmitKey(guid, aes);
            var texture = provider.LoadObject<UTexture2D>(@"/Game/UI/Foundation/Textures/Icons/Backpacks/T-Icon-Backpacks-773-Carabus-L");
            texture.Decode();

provider.LoadMappings() after submitkey

...

[TheNaeem]

still throws even if i put it after submitkey lol
