How to deploy code change? Example doesn't deploy if just an application code change. about aws-sam-terraform-examples

Looks like the depends_on isn't working the way it should, investigating:

e.g.

resource "aws_lambda_function" "publish_book_review" {
    filename = "${local.building_path}/${local.lambda_code_filename}"
    handler = "index.lambda_handler"
    runtime = "python3.8"
    function_name = "publish-book-review"
    role = aws_iam_role.iam_for_lambda.arn
    timeout = 30
    depends_on = [
        null_resource.build_lambda_function
    ]

    environment {
        variables = {
            DYNAMODB_TABLE_NAME = "${aws_dynamodb_table.book-reviews-ddb-table.id}"
        }
  }
}

Working through this, using triggers: https://discuss.hashicorp.com/t/null-resources-depends-on-doesnt-work-on-replacement/10109

K, null_resource is already using triggers and you can't use triggers on any other resource so I don't think that will work. I'm not sure there is a way as is right now.
