error handling of requests fetch #28
Description
Currently there is no error handling at all, so if an error is returned from the server it is returned to the user in its original form (for example if the API no longer works, or the user's web layer) then he receives an error from the code
The problem with this is the end customer's lack of understanding of what the problem is
Therefore need to make sure that the error returns in the form of an understandable message
