ValidationError is a type of error used to report model or any general condition validation error. We don't deal this error as a regular error i.e panic`ing, showing the error stack trace and exiting with a non zero code, otherwise, we do show a nicely formatted and user friendly error message (the What attribute) and keep returning a non zero exit code. Consider this error as a user error, not an internal malfunctioning.
