veml7700 problem with Arduino UNO Wifi Rev2

Hi.
I am using VEML7700 I2C ambient sensor from DFROBOT.
And I am handing new board "Arduino UNO Wifi Rev2" as main board.

Before new board, I used Arduino UNO board with VEML7700. It was fine.
But after changing main board, VEML7700 doesn't work.

First, when I compile, i got these messages below.

But i fixed it with this change.
//if (Wire.requestFrom(uint8_t(I2C_ADDRESS), uint8_t(2)) != 2){
if (Wire.requestFrom(int(I2C_ADDRESS), int(2)) != 2){

Still, I can't get correct ambient lux value.
The value from sensor is all the same. The value itself isn't correct I think. Because my room lux value wasn't high.
