Error: failed to list tables not authorized dynamodb

What's Causing This Error

This error occurs when the service invoking the DynamoDB ListTables operation does not have the required identity-based policy.

In simple terms, the service invoking the DynamoDB API does not have the required permissions to execute the ListTables operation.

Solution: Here's How To Resolve It

To solve the error, visit the IAM console and locate the IAM role assigned to the service. Then, attach the inline policy shown below to the IAM Role.

  "Version": "2012-10-17",
  "Statement": [
          "Sid": "allowListTablesPolicy",
          "Effect": "Allow",
          "Action": "dynamodb:ListTables",
          "Resource": "*"

Afterwards, save the changes to the role. The ListTables operation will work the next time you execute the operation via the service. However, ensure that you have added the policy to the correct role.
