This works great when the object is found, but when it's not, the input path is returned in the error message. Because this can contain newlines, the error message might get spread over multiple lines, making it harder to machine-parse this error message. With this change, the input is quote-formatted in the error message, if needed. This ensures the error message is always on a single line and makes parsing the error more straightforward.
