Deploying cube.js using serverless framework results in an error - serverless-framework

Question

I am trying to deploy cube.js project using serverless framework on aws and when I access the endpoint produced by serverless, it results in the following error on the browser
Cannot GET /
Here is my serverless.yml file
service: cloud-analytics
provider:
name: aws
stage: production
runtime: nodejs8.10
iamRoleStatements:
- Effect: "Allow"
Action:
- "sns:*"

I have followed this steps in this blog to set up NAT https://medium.com/#philippholly/aws-lambda-enable-outgoing-internet-access-within-vpc-8dd250e11e12
Cube.js file is as follows with server core options
const AWSHandlers = require('#cubejs-backend/serverless-aws');
const AthenaDriver = require('#cubejs-backend/athena-driver');
module.exports = new AWSHandlers({
externalDbType: 'athena',
externalDriverFactory: () => new AthenaDriver({
accessKeyId: process.env.CUBEJS_AWS_KEY,
secretAccessKey: process.env.CUBEJS_AWS_SECRET,
region: process.env.CUBEJS_AWS_REGION,
S3OutputLocation: process.env.CUBEJS_AWS_S3_OUTPUT_LOCATION
})
});
When I run the endpoint
https://xxxxx.execute-api.us-east-1.amazonaws.com/production/
which is produced by the serverless api gateway I get the error
Cannot GET /
On Cloudwatch I see the cubejs lambda being invoked and see logs for start and end request id. I dont see any logs on cubejsProcess lambda.
Where/How can I debug this to see where the issue is?

By default in production mode Cube.js disables dev server capability and it's why you don't see any Playground working at / path: https://cube.dev/docs/deployment#production-mode. Please use REST API to test your deployment: https://cube.dev/docs/rest-api.
