Unity allows to exclude files and folders from the “Assets” directory by prefixing them with the . or suffixing them with the ~ symbol. It’s explained in the documentation under “Hidden assets”: Unity - Manual: Special folder names
Addressables.GetDownloadSizeAsync, perhaps other Addressables APIs too, does not ignore these excluded files and causes the method call then fail.
Reproduce
- Open project on Windows
- Click in the Addressables Groups window “Play Mode Script > Use Asset Database”
- Press Play
- Press “Check for new Content”
Actual
System.Exception: Exception of type 'UnityEngine.AddressableAssets.InvalidKeyException' was thrown., Key=Assets/Textures/.keepme, Type=System.Object
Expected
No error due to excluded files and folders.
