S3UploadFailedError: Failed to upload data/train.csv to qqnl-autopilot/reuse-autopilot-blog/training_data/train.csv: An error occurred (AccessDenied) when calling the PutObject operation: Access Denied

Open Feature_selection_autopilot.ipynb and inspect cell In [4], where the training_data/train.csv upload fails. First reproduce or trace the notebook's S3 upload using the reported bucket and key, then determine the required change so the notebook completes without AccessDenied and CI passes.
