Bug Asset exists with main Type=GameObject, which is not assignable from the requested Type=GameObject

Hello.
When I try to call the Addressables.LoadAssetAsync<GameObject> method, I get the following error:

Code (csharp):

1.  
2. UnityEngine.AddressableAssets.InvalidKeyException: Exception of type 'UnityEngine.AddressableAssets.InvalidKeyException' was thrown.

Unity Editor: 2021.3.4f1
Addressables: 1.19.19

 

I got all the keys from Addressables.ResourceLocators and in the search there is a loaded asset with such a key

 

Just got the same error today trying to load from an AssetReference

Code (CSharp):

1. UnityEngine.AddressableAssets.InvalidKeyException: Exception of type 'UnityEngine.AddressableAssets.InvalidKeyException' was thrown. Could not load Asset with GUID=549302ad753399c4fb334b47fa16333f, Path=<PATH_OF_ASSET>. Asset exists with main Type=<TYPE_X>, which is not assignable from the requested Type=<TYPE_X>

called from:

saveData.scriptableObjectReference.LoadAssetAsync<TYPE_X>().WaitForCompletion();

Addressables v. 1.19.19
Unity Editor v. 2020 LTS

Has anyone else had this error? I'm not doing anything too crazy with addressables, was just attempting to serialize an assetReference to json then deserialize and load the asset as a test.

 

Same problem
Unity Editor: 2021.3.4f1
Addressables: 1.19.19
Hash Provider

 

Ah ok, figured it out, I think the error is just strangely worded which was confusing.
"Asset exists with main Type=<TYPE_X>, which is not assignable from the requested Type=<TYPE_X>"
Implied to me that the asset was registered with addressables, but was unable to cast from some reason (Asset exists sure sounds like the asset exists), but the function throws this error if it's unable to find the asset as well. Double checking and rebuilding my addressables database fixed the issue!

 

ok. it was very strange, but when I put Asset Provider in Assets from Bundles Provider, everything worked
