Amazon Sagemaker Import dataset from S3

This SageMaker Canvas error is typically related to IAM permissions or configuration issues. You could check the most common causes and solutions for your S3 import problem:

Cause & Solution:

Ensure your role has permissions to;

• "AmazonSageMakerCanvasFullAccess" policy
• S3 read/list permissions for your bucket & it's contents
• Ensure Canvas and S3 bucket are in the same region
• Check bucket policies don't block SageMaker access
• Ensure your tabular dataset is in supported format e.g. CSV, Apache Parquet, Apache ORC, JSON

Please refer: Grant Permissions for Cross-Account S3 Storage

• Your SageMaker execution role might have trust relationships with other AWS services, you can check if your role trusts services beyond SageMaker. Edit the trust policy to only include SageMaker:

        {
            "Version":"2012-10-17",		 	 	 
            "Statement": [
                {
                    "Effect": "Allow",
                    "Principal": {
                        "Service": [
                            "sagemaker.amazonaws.com"
                        ]
                    },
                    "Action": "sts:AssumeRole"
                }
            ]
        }
