Refactor the frontend data fetching functions to allow for failures

[DemonusPC]

Right now the data functions are operating on the assumption that the data will always return. This is of course not always correct. This issue proposes:

• Adding a wrapper interface to all data fetching functions. (Generic)
• The wrapper should indicate if request was successful or not
• The functions should be updated so that they do return a failure state
• Update downstream components to account for failure and success.
