ISSUES USING AS7265X SPECTRAL SENSOR WITH SPARKFUN ESP32-S2 THING PLUS

Question

So I have connected a SparkFun Triad Spectroscopy Sensor - AS7265x (Qwiic) to my SparkFun Thing Plus - ESP32-S2 WROOM using a Qwiic cable. I loaded the example code and I am only getting zeros from the sensors... No error, it throws a connection error when disconnected, just this image as the output over the serial monitor. https://i.stack.imgur.com/J9ySj.jpg

  Read the 18 channels of spectral light over I2C using the Spectral Triad

  basically do whatever you want with this code.

  This example takes all 18 readings and blinks the illumination LEDs 
  as it goes. We recommend you point the Triad away from your eyes, the LEDs are *bright*.
  
  Feel like supporting open source hardware?
  Buy a board from SparkFun! https://www.sparkfun.com/products/15050

  Hardware Connections:
  Plug a Qwiic cable into the Spectral Triad and a BlackBoard
  If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)
  Open the serial monitor at 115200 baud to see the output

I have run the Example "GetVersion" With this output: AS7265x Spectral Triad Example AMS Device Type: 0x40 AMS Hardware Version: 0x41 Major Firmware Version: 0xC Patch Firmware Version: 0x0 Build Firmware Version: 0x0

I just tested using an arduino nano connected over i2c again. Same result as the esp32's all zeros on output in serial. Im at a loss.

This was an environment issue. Ran arduino as portable and fixed....
