Learn about the common DynamoDB Error Codes. Our AWS Support team is here to help you with your questions and concerns.

Common DynamoDB Error Codes Explained

Amazon Web Services offers DynamoDB. It is a fully managed NoSQL database service. It is popular for its fast and predictable performance with seamless scalability.

This service can handle a wide range of applications, from small projects to large-scale enterprise solutions.

However, like any service, DynamoDB can run into errors. Understanding these errors and how to handle them helps with the smooth operation of our applications.

Categories of DynamoDB Error Codes

DynamoDB error codes are categorized into two main groups: 4xx and 5xx errors.

4xx Errors: Client-Side Issues

4xx errors are due to problems with the user’s request. These errors are generally due to client-side issues, like incorrect signatures, incomplete signatures, exceeding usage limits, or invalid request parameters. Here are some common 4xx errors:

• AccessDeniedException:

  This error occurs when the request has an incorrect signature.
• IncompleteSignatureException:

  This error indicates that the request has an incomplete signature.
• LimitExceededException:

  This error occurs when the limit of 50 tables and indexes in a created, updated, or deleted state has been exceeded.
• ResourceNotFoundException:

  This error happens when a request is made against a table that does not exist.
• ValidationException:

  This error signifies that the request failed validation, was not permitted, or exceeded certain limits.

5xx Errors: Server-Side Issues

5xx errors are due to problems with the AWS service itself. These errors can often be resolved by retrying the request. Here are some common 5xx errors:

• InternalServerError (HTTP 500):

  This error means that DynamoDB could not process the request due to an internal server error.
• ServiceUnavailable (HTTP 503):

  This error indicates that DynamoDB is currently unavailable.

Handling DynamoDB Errors

1. Wrap DynamoDB Operations with “try-catch” Blocks:

   This method helps manage exceptions and errors effectively. Thus allowing the application to respond appropriately.
2. Leverage Built-in Error Handling and Retry Mechanisms:

   DynamoDB SDKs come with built-in mechanisms for handling errors and retries, making it easier to manage issues.
3. Customize SDK Behavior Around Retries:

   We can provide custom configurations to adjust how the SDK handles retries, tailoring it to better suit the application’s needs.
