Hello!
I’m currently trying to integrate the prototype to my site using Embed API. As it was requested in the instruction, I’ve created a new application, added allowed embedded origins and inserted iframe tag with prototype URL (including client-id field in order to enabled Embed API). However, it seems that my origin settings aren’t propagated to the iframe. Whenever I click to the prototype inside the iframe, my browser logs an error message into the console. From what I already discovered, allowed_embed_origins field always comes with null value, regardless of the settings I set. Please take a look
My embed API settings, application isn’t published and is still set to “private”

Error messages (they’re the same on any of the specified origins)

Reproduced in latest Chrome and Firefox browsers
