Express router issue when using a custom domain name

Hi, I am using aws-serverless-express for exposing the express router endpoints. The endpoints work when the generated API gateway is used as it is. e.g https://711111abcde.execute-api.ap-southeast-2.amazonaws.com/dev/health. But after mapping this hostname to a custom domain (https://api.myapp.com), the endpoints do not work. The same custom domain endpoints work when the lambdas are not in express app.

My Code:

const app = express();
app.use(cors())
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({ extended: true }))
app.use(awsServerlessExpressMiddleware.eventContext())

app.get('/health', (req, res) => {
  console.log('APP health1: ');
  res.status(200).json({ status: 'Next() API Health is OK and now ready to process requests...' });
});

The custom domain gives the headers as "x-powered-by’ : express. This says that my requests hit the express app but somehow never routed to any of the endpoints configured.

const awsServerlessExpress = require('aws-serverless-express');
const route = require('./route');
const server = awsServerlessExpress.createServer(route);
exports.handler = (event, context) => awsServerlessExpress.proxy(server, event, context);

Are there any more configuration needed for custom domain (API Gateway). Please advise

@Mohan1996 - You can do the following:

• Get the @turinggroup/serverless-express-custom-domain-middleware npm package
• Then use it in your route.js or whichever file you are using for configuring your express routers const customDomainReroute = require('@turinggroup/serverless-express-custom-domain-middleware').customDomainReroute const app = express(); app.use(customDomainReroute)

Rest of the code is as it is used in any express route js. The above npm package helps in resolving the basePath that has been setup in API GW for a custom API domain (e.g https://api.myapp.com)
