Lambda Configuration

Here is how the part of index.js, which is used to run the app on AWS Lambda, looks like:

'use strict';

const {app} = require('./app/app.js');

exports.handler = (event, context, callback) => {
    app.handleLambda(event, context, callback);
};

• Run your Google Action on Lambda with an API Gateway

Things to Consider

Troubleshooting

If your tell or ask responses aren't firing inside callbacks or promises on Lambda, try to add the following to your exports.handler:

context.callbackWaitsForEmptyEventLoop = false;
