webp problems with image generation

[Ralf]

Hello everybody,

in order not to hijack the Wishlist & Roadmap thread, here is an extra thread about my current webP problem where I need your help.
More precisely, it's about a strange phenomenon in the creation of images.
- I have an Image Field, where I can upload an image.
- Then I save the page with the image and call up the internet address in the frontend.
- PW now generates a webP image for me.
=> HOWEVER this picture is unfortunately "empty"....

More details see in this article here:

Help where is my error? Is it PW? is it the GD version I use?

Thanks Ralf
