Hi @marco910, This may very well be expected. The prebuilt binaries for sharp only support AVIFs with a bit-depth of 8, so this likely isn't something we're going to be able to get working. I will however, include a task to update the documentation/returned error to make that more clear.

Thanks, Simon

Hi @simonkrol ,

Thanks for the explanation. When testing with an 8-bit AVIF, the transformation works fine.
