webpack returned errors to ember-auto-import

I saw @babel/plugin-syntax-bigint could do the job but i don't know how to configure this plugin ?

I don't think @babel/plugin-syntax-bigint can help us here. That allows babel to parse the code, but it's not babel that is failing here, it's webpack.

Webpack uses acorn as its parser, and there does appear to be an acorn-bigint plugin that can parse bigint, but unforunately webpack doesn't let you add plugins to acorn. See for example webpack/webpack#10216 (comment)

However, from some quick testing it looks like the newest webpack builds in support for bigint. It should be enough for us to upgrade the version of webpack that ember-auto-import is using. We have been pinned to a slightly older version due to an npm bug that breaks users of webpack after 4.29.0 (see #192 (comment)). But it's probably time to just try jumping ahead and hope the dependencies have shuffled enough that the npm bug doesn't bite much.

Let's see if we can release #299

I have fixed the webpack dependency in my yarn.lock => this is working. ember build as well

now if I build the production env,
the build is fine, but when i ask for the route
I got this error :
