Is not authorized to perform: dynamodb:query on resource: This error message can be quite frustrating for developers who are trying to interact with Amazon DynamoDB. It indicates that the user or the role associated with the user does not have the necessary permissions to perform a query operation on the specified resource. In this article, we will explore the common causes of this error and provide solutions to help you resolve it effectively.
Amazon DynamoDB is a fully managed, serverless, key-value NoSQL database service provided by Amazon Web Services (AWS). It allows developers to easily build and run applications that require fast and predictable performance at any scale. However, to access and manipulate the data stored in DynamoDB, proper permissions must be set up in the AWS IAM (Identity and Access Management) system.
One of the most common reasons for encountering the “is not authorized to perform: dynamodb:query on resource:” error is insufficient permissions. When you try to perform a query operation on a DynamoDB table, the AWS IAM system checks if the user or role has the necessary permissions. If not, the system will return this error message.
Here are some steps you can take to resolve this issue:
1. Verify the IAM role or user’s permissions: Check the IAM policies attached to the role or user that is trying to perform the query. Ensure that the policy includes the necessary permissions for DynamoDB. The policy should grant the “dynamodb:Query” action on the specific table or on the DynamoDB service itself.
2. Check the resource ARN: The error message might indicate that the user does not have permissions on the specified resource. Double-check the resource ARN (Amazon Resource Name) to ensure that it is correct. The ARN should match the DynamoDB table name or the service name.
3. Grant the necessary permissions: If the user or role does not have the required permissions, you need to modify the IAM policy to grant the “dynamodb:Query” action. You can do this by either creating a new policy or modifying an existing one. Here’s an example of a policy that grants query permissions on a specific DynamoDB table:
“`
{
“Version”: “2012-10-17”,
“Statement”: [
{
“Effect”: “Allow”,
“Action”: “dynamodb:Query”,
“Resource”: “arn:aws:dynamodb:region:account-id:table/table-name”
}
]
}
“`
4. Attach the policy to the role or user: Once you have created or modified the policy, attach it to the appropriate IAM role or user. This will grant the necessary permissions for the query operation.
5. Test the query operation: After updating the permissions, try to perform the query operation again. If the error persists, double-check the policy and resource ARN, or contact AWS support for further assistance.
In conclusion, the “is not authorized to perform: dynamodb:query on resource:” error can be resolved by ensuring that the user or role has the necessary permissions for the DynamoDB query operation. By verifying the IAM policies, checking the resource ARN, and granting the required permissions, you can successfully resolve this issue and continue working with Amazon DynamoDB.
