Followed notebooks samples for CPR and deploy but getting FailedPrecondition

Follow this tutorial: https://github.com/GoogleCloudPlatform/vertex-ai-samples/blob/main/notebooks/community/prediction/custom_prediction_routines/SDK_Custom_Predict_SDK_Integration.ipynb

Not sure how to debug this. Perhaps a bit to add is that I am quite familiar with the GCP ecosystem and I did try several ways to deploy this.
