I have the WP-Stateless but upfront stops work with that...

Hi there, i have the WP-Stateless plugin, and now, i think that upfront stops working with that... In the last versions the upfront works perfectly with this plugin, i have the media set to use google storage like a cdn, but now, the upfront set some url parameters in the images that is't correctly for this plugin, and the images have a 404 error. I see the images in the upfront editor, but qhen i save the configuration, the images appear with a 404 error in the front end.
