To load and configure the prototype Lambda function:

1. Select Functions on the left menu.

2. Select the function just created.

3. Select Upload a Zip File under the Actions drop-down button.

.....a. Click the Upload button.

.....b. Find the zip file downloaded for the Lambda function in your file system (protolambda.zip).

.....c. Click the Save button.

4. Click the test button at the top.

5. Choose Create New Test Event.

.....a. Enter an Event Name (i.e., pTest).

.....b. There is no need to configure test parameters as the prototype application relies on URL query parameters.

.....c. Click on the Create button.

.....d. Under Runtime Settings, update the handler to show the starting point for your application (i.e. appAdminService.lambda_handler).

.....e. Select the Test Event and run a test. It will have errors saying no query string. This is OK since the function is designed to run from the API Gateway.
