With the ESP32, depending on what board you are using the SDA and SCL default pins might be different. If that's an ESP32 WROOM dev kit, then your SDA pin is 21 and your SCL pin is 22 by default. Or you can simply use:
Wire.setPins(, );
and substitute whatever pin numbers you are using for SDA and SCL. You just have to do this before the Wire.begin() command.
