Exposing raw validation errors in the API response could leak internal implementation details. Consider sanitizing or formatting these errors for public consumption.

	# Sanitize errors for public consumption
	sanitized_errors = [
	{"loc": error.get("loc"), "msg": error.get("msg")}
	for error in errors
