Ionic cordova resources --splash and --icon error

Question

I´m getting this error on resources generator:
Error: end() has already been called, so it's too late to start piping

I´m stuck with this error. Shows up when I try to generate resources:

PS F:\Desenvolvimento\Ionic\Divas> ionic cordova resources ios -f

√ Filtering out image resources that do not need regeneration - done!

Answer 1

It looks like my image was incorrectly sized. I created a new image with larger sizes and it worked. Strange that there was no message about it.
