// to unmarshal the JSON content into the provided `dest` interface.

// The response body (w.Body) is then restored so it can be read again later, if necessary.
//
// Parameters:
//   - dest (interface{}): A pointer to the destination where the parsed JSON
//     from the response body will be stored. It can be a struct or map that matches
//     the JSON structure.
//
// Returns:
// - error: Returns an error if the reading of the body or the unmarshalling process fails.
