Run ionic cordova resource --verbose please.
Also make sure the source images are not 0x0px of size.

The same error here. The command with --verbose has the same output:

Thanks for the --verbose output, unfortunately nothing helpful.

What are the filenames of your files?
Are the file types correct?
What is the size (file size and image size) of your files?
