A graphics design company is experimenting with a new feature for an API and the objective is to pass the field "color" in the JSON payload to enable this feature. The new Lambda function should treat "color": "none" as a request from an older client. The company would like to only have to manage one Lambda function in the back-end while being able to support both old and new clients. The API Gateway API is currently deployed on the v1 stage. Old clients include Android applications which may take time to be updated. The technical requirements mandate that the solution should support the old clients for years to come. As an AWS Certified DevOps Engineer Professional, which of the following options would you recommend as the best fit for the given use-case?
