🐛 bug report

🎛 Configuration (.babelrc, package.json, cli command)

      "@babel/plugin-transform-runtime",
      {

Installing browserslist package manually fixed the issue

After getting the project to build i get the following error in the console that wasn't there previously

Just as a note it's working perfectly in development

[DeMoorJasper]

Please try 1.10.1

[scrossan-crown]

I've tired 1.10.1 and it's not having the above error but is now having a completely different error when building.

Error: Minified React error #130; visit https://reactjs.org/docs/error-decoder.html?invariant=130&args[]=undefined&args[]= for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

[scrossan-crown]

I'm not sure if it helps but I've changed one route component to import the component directly instead of using react-loadable and async imports and it works perfectly

[DeMoorJasper]

@scrossan-crown well that looks like a react error. If that also happens in a dev build it’s a bug in your code

[scrossan-crown]

@DeMoorJasper the issue is that there are no errors in the dev build but the production build is broken as of 1.10.0-beta.1

[DeMoorJasper]

Not sure if I’ll be able to do anything without a minimal reprodcuable example. It seems to be a minification issue but we didn’t change any minification in 1.10 afaik

[scrossan-crown]

Ok, I’ll have a play around and try to get a reproducible example up and running.

I think I've found the error, it was a case of the localStorage containing some incorrect data. Thanks for your suggestions and help
