Deploy to Luxonis OAK code provided by Roboflow does not work

I already tested all the depthai demos on my OAK device. Every demo is working fine but when I’m using the Luxonis OAK code provided by Roboflow (Luxonis OAK (On Device) - Roboflow) for my object detection project on my Raspberry Pi 4 I always get the Key-Error ‘colors’, more detailed:

Traceback (most recent call last):
File “home/pi/”, line 8, in
rf=RoboflowOak(model=“schwimmen-cp33a”, confidence=0.05, overlap=0.5,
File “/usr/local/lib/python3.9/dist-packages/roboflowak/”, line 46, in init
KeyError: ‘colors’

roboflowoak is on the latest version 0.0.8, python at 3.9.

I’m looking foreward for your suggestions.

Best regards,
