Access Denied for Data Analysis and Visualization in AWS Workshop

Question

I am closely following the Data Analysis and Visualization in AWS wokrshop. Once I create a job in Glue Databrew and select the role that we set up with the permission given by the workshop, I get this error:

```
Access denied to s3:ListBucket for arn:aws:iam::311516367207:role/AWSGlueDataBrewServiceRole-data-analyst for location s3://my-bucket-311516367207/data-analysis-lab/. Error: Access Denied
```

Howver, when I run the permission simulator from my admin account, it says that the user does have permission to list bucket. I even redid the entire workshop from the beginning, and it still marks this error.

Answer

Ensure that the **IAM role** `AWSGlueDataBrewServiceRole-data-analyst` has trust relationships with the **Glue** service. Here's a sample trust policy assuming Glue is the service requiring access:

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

```
Update the **IAM policy** attached to the role `AWSGlueDataBrewServiceRole-data-analyst` to allow the necessary **S3** actions (s3:ListBucket, s3:GetObject, etc.) on the specific bucket (`s3://my-bucket-311516367207/data-analysis-lab/`). Here's a sample **IAM policy**:

```
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "s3:ListBucket",
        "s3:GetObject"
      ],
      "Resource": [
        "arn:aws:s3:::my-bucket-311516367207/data-analysis-lab",
        "arn:aws:s3:::my-bucket-311516367207/data-analysis-lab/*"
      ]
    }
  ]
}

```

(Optional): Ensure that the **S3 bucket** (`my-bucket-311516367207`) has a policy allowing the necessary actions for the **IAM role**. Here's a sample bucket policy:

```
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::311516367207:role/AWSGlueDataBrewServiceRole-data-analyst"
      },
      "Action": [
        "s3:ListBucket",
        "s3:GetObject"
      ],
      "Resource": [
        "arn:aws:s3:::my-bucket-311516367207/data-analysis-lab/",
        "arn:aws:s3:::my-bucket-311516367207/data-analysis-lab/*"
      ]
    }
  ]
}

```
