Error to Test the model - RestAPIError: Metadata operation error

Hi everyone,
I’m trying to run the ‘air_quality’ notebooks on my local computer, but I ran into an issue in the third step: air_quality/3_training_dataset_and_modeling.ipynb at main · jimdowling/air_quality · GitHub

For the TEST MODEL session, I ran into an error.

RestAPIError: Metadata operation error: (url: Server response:
HTTP code: 422, HTTP reason: UNPROCESSABLE_ENTITY, error code: 120001, error msg: An argument was not provided or it was malformed., user msg: Invalid requested features

I tried to learn more about the function ‘get_batch_data’, but I couldn’t find a solution for this issue. Would you mind giving me a hand to solve it, please?
Thanks for your time,
