JavaScript does not get loaded on the custom _error.js page

None of my JavaScript gets loaded on the custom _error page in a production bundle, works fine in development though.

There’s also things on the _error page that are reused elsewhere in the application like a common header that has some JavaScript for letting a user log in/sign out.

In the console I can see some errors saying the scripts can’t be found. Is this normal behaviour that you simply can’t run any JavaScript on the _error page? Is there any way to hack around this?

• I have searched the issues of this repository and believe that this is not a duplicate.

Steps to Reproduce (for bugs)

1. Create a custom _error.js page in the pages folder that’s part of next’s api
2. Go to a route that doesn’t exist

Context

I was asked to implement a newsletter subscription form on the custom error page in order to give the user the ability to be notified as soon as a certain page exists because we have links that don’t lead anywhere yet for a second stage of the project.

The error is actually pretty clear,

["babel-plugin-root-import",
            [
                {
                    "rootPathPrefix": "~"
                },
                {
                    "rootPathPrefix": "@",
                    "rootPathSuffix": "src/components"
                },
                {
                    "rootPathPrefix": "#",
                    "rootPathSuffix": "src/utils"
                }
            ]
        ],

this must be an object. Seems like it’s an open pull request here: https://github.com/entwicklerstube/babel-plugin-root-import/pull/93

Also ["transform-define", "./env-config.js"] must be an object too, you can do this using .babelrc.js: https://github.com/zeit/next.js/issues/4239#issuecomment-385775369

Going to close this as it works fine on latest.
