Don't work correctly with url containing "&"

[rvelati]

I enabled SXG on the site: https://www.iltelegrafolivorno.it through Cloudflare.
In our site images are composed with this url:
i.e:
https://www.iltelegrafolivorno.it/immagini/?fmt=webp&url=http%3A%2F%2Fp1014p.quotidiano.net%3A80%2Fpolopoly_fs%2F1.7801291.1655663245%21%2FhttpImage%2Fimage.jpg_gen%2Fderivatives%2Fwidescreen%2Fimage.jpg&w=512

using the sxg-validator it return me an error in the cache:

returning:
199 - "debug: content has ingestion error: Error fetching resource: not found"

but if I check the cache directly it works:

ie:
https://www-iltelegrafolivorno-it.webpkgcache.com/doc/-/s/www.iltelegrafolivorno.it/immagini/?fmt=webp&url=http%3A%2F%2Fp1014p.quotidiano.net%3A80%2Fpolopoly_fs%2F1.7801291.1655663245%21%2FhttpImage%2Fimage.jpg_gen%2Fderivatives%2Fwidescreen%2Fimage.jpg&w=512

It looks like it's working now when I tried that url with the validator:
https://www.iltelegrafolivorno.it/immagini/?fmt=webp&url=http%3A%2F%2Fp1014p.quotidiano.net%3A80%2Fpolopoly_fs%2F1.7801291.1655663245%21%2FhttpImage%2Fimage.jpg_gen%2Fderivatives%2Fwidescreen%2Fimage.jpg&w=512

It's possible that what you were seeing is that the signed exchange hadn't made it to the cache yet, that's why the ingestion error was being displayed.
Could you try it again from your end to see if you're still seeing the error? Thanks.
