• Log into the AWS console using the given credentials for the lab session.
• Proceed to step: Custom Authorizer Use Cases and read the details. Once done proceed to the next step.
• Once on this step: Creating a Simple API Gateway Endpoint

• Name: HelloWorld
• Runtime: Select Node.js 14.x (The latest version of Node.js 14)
• Click Change default execution role
• Select Use an existing role, Existing role: Select lambda_basic_execution:

• Click Create function and you will be able to create the function successfully:

• Scroll down to the Code source section, double-click the index.js file, and overwrite the contents with the provided code in the instructions:

• Once done, click deploy:

• Now go to the functions view and add a trigger: In the Trigger configuration panel, choose REST API as Choose a template option and select Open under Security:
