Socialcademy 11, Accessing the Camera Roll & Taking Photos

I am facing a problem with tutorial 11 for Socialcademy, I did all the steps in this article but unfortunately the app doesn’t work as it suppose to, when I try to post a new post with an image, it display an error in the console that says " objectNotFound(“posts/164A5153-E63D-479F-BB07-972774F3A580”)". but when I try to create a post without an image it works. I even tried the completed code for this tutorial but it also didn’t work.

problem is solved, to be able to add images, you must open the storage section in firebase and edit the rules to “true” instead of false to be able to add the image to posts.
