An error in "enabled_bundles" configuration triggers a Webpack error

I misconfigured this Bundle by using this configuration:

maba_webpack:
    enabled_bundles:
        - "FooBundle"

FooBundle exists but didn't contain any call to webpack_asset().

I had an error when I compiled through webpack:

$ app/console --env=prod maba:webpack:compile

I think the root of the problem is in the app/cache/prod/webpack.config.js file:

module.exports = require("\/…\/app\/config\/webpack.config.js")({"entry":[],"groups":[],"alias":{"@ENPCPortailBundle":"\/…\/src\/ENPC\/PortailBundle","@npm":"\/…\/node_modules","@composer":"\/…\/vendor","@root":"\/…"},"manifest_path":"\/…\/cache\/prod\/webpack_manifest.json","environment":"prod","parameters":[]});

Note the empty "entry":[] node.

I think that there should be a check when Twig files are parsed and that no entry point is found, in order to display a warning instead of creating a webpack.config.js file that will break Webpack.
