Lambda functions associated with the API Gateway endpoints will now process uploaded images and return data about those uploaded images.

Each Lambda function servers a specific purpose. Upload accepts an image file and writes it to an S3 bucket. The List function returns a JSON array of all the uploaded files.

• S3
• IAM

The GET /api/images endpoint is not functioning. Compare the List Lambda function resource to the Upload functionn and add the missing elements required to grant S3 read permissions.

Reference the SAM Policy Templates documentation to find the appropriate role.

As an additional challenge make use of SAM's Globals feature.
