Cannot set property 'warmUp' of undefined

See original GitHub issue

I’m getting the following error:

{ "errorType": "TypeError", "errorMessage": "Cannot set property 'warmUp' of undefined", "trace": [ "TypeError: Cannot set property 'warmUp' of undefined", " at Module.<anonymous> (/var/task/_warmup/webpack:/_warmup/index.js:9:1)", " at Module.module.exports (/var/task/_warmup/index.js:146:30)", " at __webpack_require__ (/var/task/_warmup/webpack:/webpack/bootstrap:19:1)", " at /var/task/_warmup/webpack:/webpack/bootstrap:83:1", " at Object.<anonymous> (/var/task/_warmup/index.js:87:10)", " at Module._compile (internal/modules/cjs/loader.js:776:30)", " at Object.Module._extensions..js (internal/modules/cjs/loader.js:787:10)", " at Module.load (internal/modules/cjs/loader.js:653:32)", " at tryModuleLoad (internal/modules/cjs/loader.js:593:12)", " at Function.Module._load (internal/modules/cjs/loader.js:585:3)" ] }

Any ideas? It’s proving challenging to debug.

As a reference for anyone else running into this.

We recently upgraded our node runtime to 10.15 and in the process our babelrc lost the commonjs module. Adding it back in fixed things.
