Partially Addressed Error Handling for API Route

[MatthewTran22]

Some parts, like the check for duplicates or input validation, don't have dedicated methods.
Input validation only checks if the SKU isn't empty
Checking for duplicates is not implemented, so the error handling is not created yet
All other cases are handled

left some comments/suggestions!

this is catching an exception then raising another exception which isn't caught. perhaps we can change this so that the exception is caught. (maybe we raise it in the try block instead of the catch block?)
