Changelog Entry

Description

Unified the logic about selecting the model into the new function get_model that throws a consistent exception in case the model is not defined. This also fixes the issue that in some instances the model selection wasn't properly throwing a descriptive exception.
Unified the logic that transforms an exception into a JSONResponse handling both the HTTPException object and the generic Exception object. This fixes the issue that sometimes the e.args tuple did not contain enough items to properly construct the JSONResponse

Added

Unified logic for selecting the model in get_model
Unified the logic that transforms an exception into a JSONResponse in exception_json_response

Changed

Updated the code to take advantage of the new functions get_model and exception_json_response

Fixed

Selecting an undefined model returns an informative error message
Base exceptions are now properly handled and they don't result into an index error for the tuple e.args
