If message is empty and debug > 1 out of index is thrown about whr_930

my fix would be:

def debug_data(serial_data):
    if not debug is True:
        return

    if not serial_data is None:
        
        if debug_level > 0:
            data_len = len(serial_data)
            if data_len == 2 and serial_data[0] == "07" and serial_data[1] == "f3":
                print(
                    "Recieved an ack packet: {0} {1}".format(serial_data[0], serial_data[1])
                )
            else:
                print("Data length   : {0}".format(len(serial_data)))
                print("Ack           : {0} {1}".format(serial_data[0], serial_data[1]))
                print("Start         : {0} {1}".format(serial_data[2], serial_data[3]))
                print("Command       : {0} {1}".format(serial_data[4], serial_data[5]))
                print(
                    "Nr data bytes : {0} (integer {1})".format(
                        serial_data[6], int(serial_data[6], 16)
                    )
                )

                n = 1
                while n <= int(serial_data[6], 16):
                    print(
                        "Data byte {0}   : Hex: {1}, Int: {2}, Array #: {3}".format(
                            n, serial_data[n + 6], int(serial_data[n + 6], 16), n + 6
                        )
                    )
                    n += 1

                print("Checksum      : {0}".format(serial_data[-2]))
                print("End           : {0} {1}".format(serial_data[-2], serial_data[-1]))

        if debug_level > 1:
            n = 0
            while n < data_len:
                print("serial_data {0}   : {1}".format(n, serial_data[n]))
                n += 1

    else:
        print(f"serial_data ({serial_data}) is empty")`
