Problems
All errors from the api are returned in the form of "problems" (response body), except for the http status code itself.
The problem object contain more detailed info on what the error is. The "type" property can be used to programmatically interpret the error as it contains a code definition of the problem.
Other properties can be useful for logging and subsequent troubleshooting. Some problems are extended with additional parameters so it may be a good idea to log response body as raw data to include these.
Problems of type validation does contain an additional list ("Problems") that describes exactly which parameter that failed the validation
