What's Causing This Error

There can be many reasons why this kind of error arises when trying to run the DynamoDB Local service in a Docker container. For instance, it can be due to an incorrect image name, an issue with port mapping, volume mapping, or a network issue.

Solution: Here's How To Resolve It

The way to resolve this error depends on the root cause of the issue. For instance, you can start by rechecking and verifying the below points to determine the cause and take appropriate actions.

• Ensure your docker run command contains the correct image name for DynamoDB Local (amazon/dynamodb-local).
