Within the range from startSleepTracking() to stopSleepTracking(), if a network error occurs, it used to return the common error code ERR_NETWORK(11500). Now, I have added different error codes, ERR_CREATE_FAILED(22500) and ERR_CLOSE_FAILED(24500) for distinguishing purposes.
For functions like initAsleepConfig(), getReport(), getReports(), deleteReport(), and deleteUser(), if a network error occurs, it will now return ERR_NETWORK(11500).
