I don’t know much about Adobe DPS, but if it’s rendering an HTML canvas locally you might need to tweak the embed code slightly. At present it assumes an http or https URL. Maybe DPS is not returning that as the protocol?
In the embed code, you’ll see a reference to //platform.twitter.com, change that to https://platform.twitter.com.
Not being aware of the DPS feature-set, I’m not sure I can promise you full support on a platform like this—it really depends on how completely it implements the browser vs being a rendering canvas. I don’t know, for example, what it will do when you click on a Tweet action to Reply or RT. If you’re working with it though, would love to hear how you get on. If there are blockers we can at least track them and consider them for future updates.
Thanks,
Ben
