Unsure Set-up
I couldn't find where the code has the SCK and SDI pins wired to so I went with the default and wired them in the raspberry pi 4b to the SCL and SDA pins. The sensor is on and powered correctly but I not sure exactly where to wire sensor to on GPIO pins. I am currently getting this error:

if anyone knows what this error means please let me know how I can fix this issue
I2C pins are GPIOs 2 and 3 - https://pinout.xyz/pinout/i2c
A photo of your wiring setup might help with diagnosis.
You can also use i2ctools:
sudo apt install i2c-tools
And check what devices your Pi can see on the I2C bus like so:
sudo i2cdetect -y 1
