Replacement index 1 out of range for positional args tuple

[Pythonaire]

This error comes up continuously. If im right, this error is produced by

value = decode_value(object_info.response_data_type, frame.data)

Mostly, this error is produced while reading/decoding "dc_conv.dc_conv_struct[1].p_dc_lp". But i think it is not related to a special value.
