GetImageDataAsync throws an Object reference error

After editing an image, I get the image data from the editor (which I was previously doing with 

GetImageDataUrlAsync and converting that to base64 string and then to a byte[]) so I can save it.

After updating from to 23.2.7 to 24.1.46, GetImageDataUrlAsync throws a null object reference. I tried

GetImageDataAsync instead but that throws the same error:

Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]

      Unhandled exception rendering component: Object reference not set to an instance of an object.

System.NullReferenceException: Object reference not set to an instance of an object.
