Bug: better error handling for app

[JamesHWade]

When an API is unsuccessful, the current implementation in the app doesn't alert the user. This is confusing because the user doesn't know if they should keep waiting. Better error handling for these cases would be a better user experience.

I think this inherits the lack of focus in error handling in the standard request api model #111 . I've had some failed requests but I don't think the logs show error messages or warnings since v0.3.0. We need to adjust our tests and might even need to start testing in Github Actions?
