TypeError: Cannot read property 'match' of undefined

I ran across this error today, and was thoroughly confused. I also found the solution, so wanted to share in case others hit the same thing!

The error:

TypeError: Cannot read property 'match' of undefined

The cause

I had changed the example code:

server.js

- const routes = require('./routes');
- const handler = routes.getRequestHandler(app);
+ const { getRequestHandler } = require('./routes');
+ const handler = getRequestHandler(app);

Ie; I had introduced a destructruing require, which resulted in the above error.

The fix

Stick with a non-destructured require like the docs show:

server.js

const routes = require('./routes');
// ...
const handler = routes.getRequestHandler(app);
