Moved functions into service - Failed to load component state

and so I recently moved all my functions into a new service page so I can easily pass data between other pages, I can still login to my firebase ionic angular app but when attempt to load the posts page, it’s blank, Augury is telling me: Failed to load component state on my ion-list, I can see there is 4 posts but they are not loading up in the browser, please help?
I am providing the service in my feed.ts page although would be nice to provide it from my app.module.ts.

One step at a time, I’d like to get my posts showing first


See: The Angular Style Guide - Services

Thanks, I am injecting and believe I am doing everything the style guide suggests.
