Is there anything else in this error? We use create-react-app in our Quick Start and it works: https://auth0.com/docs/quickstart/spa/react/01-login#create-a-sample-application

Further output. I've tried updating to react-script 3 with no luck also. The project I'm working on is ejected which makes updating to the latest CRA scripts troublesome.

@benlester did you try in a non-ejected project like our Quick Start?

[benlester]

Yes I've tried in a non-ejected dummy project and yes it does indeed work. The problem is this project is a behemoth project which was ejected a long time ago - quite difficult to put the genie back in the bottle.

The project works perfectly fine with npm run start it just refuses to build a minified version of auth0-spa-js

[luisrudge]

Maybe it’s trying to process the file again? Make sure you exclude the node_modules or, if you need to process other libs, exclude this specific directory.

If you put a repro project somewhere, I’ll try to help. For now, I’m closing it because looks like a configuration issue.

[benlester]

For what it's worth to anyone who may read this in the future.

I solved this issue by creating a dummy app with CRA, then copying the configs and scripts folders over to the project. And then updating the package.json file against the new dummy app's package.json.
