What does it mean when "module '@aws-sdk' cannot be found in Node.js"?

edit

This error message means that Node.js is unable to find the required AWS SDK module named '@aws-sdk'. This could happen due to several reasons such as missing dependencies or packages, incorrect module naming or versioning, or improper configuration of the project. To resolve this issue, you can try installing the required dependencies or packages, verifying the module name and version, or checking if the AWS SDK is correctly configured.
