How can I access the data from blob storage through script.py using online endpoint?

Hello,

I have deployed an MLflow classification model through an online endpoint. To obtain customized output from the endpoint, I have included a score.py.

This script.py is designed to retrieve data from blob storage/data assets using the customer number as input, and then utilize the features to generate prediction probabilities.

However, I'm encountering a "read permission error."

I am attaching the error as a screenshot here, kindly help.
