The image is successfully compressed, but the output is a file that weighs 0 bytes

I compress an image weighing 1.9 mb and a resolution of 750 by 16000 pixels (16000 pixels - length), and the output I get an image weighing 0 bytes in the format .webp, with other large images are fine.
What can be the problem? A piece of code is taken from the convert.rs example.
