I’m new to python, but since we are trying to use GRIP on the pi this year we’ve decided to take on this task. I have my code vision code, but we keep getting an this error.

You’re using NetworkTables code from last year, the API is different this year. See the documentation for details: API Reference — RobotPy NetworkTables 2021.0.0 documentation
