Better handle API scope issues #34
Description
Right now, we do not have any proper error handling for API responses that do not contain data in the structure we expect. This can be because of an API issue, but most of the time it's due to the user not configuring the API scopes before usage.
We should have some error handling around the Caracara calls to ensure that we do not 'crash', and we give useful output to the user if something fails.
This may be related to #33.
