On the Advanced Function Details screen, select the same role which you created in the first exercise (that role has access to the AWS Systems Manager Parameter Store and the encryption key).
The upload will start the function deployment. The deployment screen will close and test screen will open as soon as the AWS Lambda function is uploaded successfully.
Type in any string as input (as input has no meaning here) and then click on the
