Error: dynamodb problem function call failed

“Function call failed” is too general to identify a DynamoDB fault. It can be an application, framework, or integration wrapper around a more specific exception. Preserve the original error and determine whether the request reached DynamoDB.

try {
  await db.send(command); // Existing SDK v3 client and command.
} catch (error) {
  console.error({
    name: error.name,
    message: error.message,
    status: error.$metadata?.httpStatusCode,
    requestId: error.$metadata?.requestId
  });
  throw error;
}

• ValidationException: inspect the named request field, key type, or expression. Retrying unchanged input will not fix it.
• AccessDeniedException or a credential error: check the active identity, credential provider, and required action.
• Connection or DNS error: verify the endpoint and network route from the failing runtime.
• A retryable service error: use SDK backoff and retain request IDs for investigation.

Check the application or Lambda logs where the exception occurred. DynamoDB does not automatically place every application request and stack trace in your CloudWatch log groups. If a wrapper hides the cause, reproduce the same operation with a minimal SDK request before choosing a fix.

See specific DynamoDB errors and AWS documentation.
