A fatal error occurred: Serial data stream stopped: Possible serial noise or corruption. on ESP32 #44

`#include <IBusBM.h>

IBusBM ibus;

// If the channel is off, return the default value
int readChannel(byte channelInput, int minLimit, int maxLimit, int defaultValue) {

I use it on an esp32 based board (Waveshare General Driver for Robots) using esp32 Dev Module on Arduino IDE. and i get the following errror on compilation.
A fatal error occurred: Serial data stream stopped: Possible serial noise or corruption.
Failed uploading: uploading error: exit status 2

I connected the pins as instruxted.
