How to deploy code change? Example doesn't deploy if just an application code change.

I was able to deploy with Terraform the example at zip_based_lambda_functions/lambda-example/main.tf. However, if I just change a line in the zip_based_lambda_functions/api-lambda-dynamodb-example/src/index.py and do another `terraform apply`, the output rebuilds the file, yes, but it never deploys it.

This article doesn't suggest how to deploy changes.

Here is the tail of an apply:


Start with zip_based_lambda_functions/lambda-example/main.tf and zip_based_lambda_functions/api-lambda-dynamodb-example/src/index.py, then reproduce the reported behavior with terraform apply after changing a line. Document the steps or configuration needed for an application-code change to deploy, and verify that the documented workflow updates the deployed function.
