i didnt see where the I2C_BUFFER_LENGTH define and i keep getting error becuase of this what am i missing?

I'm using the Arduino espressif32 framework and that has a value of 128 defined in Wire.h but this may vary depending on your target framework/microcontroller.

Looks like the default i2c buffer size for AVR chips is 32. You can just add #define I2C_BUFFER_LENGTH 32 before the include.
