pre-certification, cobalt can't render webp page

manpreet Best Answer 3 years ago

For YouTube pre-certification, cobalt needs to render some pages that YouTube assigned.
We test the three commands below:

./cobalt --url=http://www.gstatic.com/webp/gallery/1.webp --allow_http --csp_mode=disable
./cobalt --url=http://www.gstatic.com/webp/gallery/1.webp --disable_navigation_whitelist
./cobalt --url=http://www.gstatic.com/webp/gallery/1.webp --disable_navigation_whitelist --allow_http

but cobalt renders nothing. Could someone guide us on how to render a webp page for pre-certification?
