bug(next): next@10.1.3 webpack hook issues

[ryan-roemer]

It looks like a monkey-patch for node internals for webpack to decide between 4 and 5 around this code: https://www.runpkg.com/?next@10.1.3/dist/next-server/server/config.js#397 (after prettifying)

await (0, _configUtils.loadWebpackHook)(phase, dir);

produces this error because of missing files, where awkwardly it looks like we have to include webpack even though we don't want to use it at runtime:

"Error: Cannot find module 'next/dist/compiled/webpack/webpack-lib'",
        "Require stack:",
        "- /var/task/node_modules/next/dist/build/webpack/require-hook.js",
        "- /var/task/node_modules/next/dist/next-server/server/config-utils.js",

We could just trace and package those files, but it would be nice to not bloat the package.

We've bandaided this with a tracing configuration like this: afc7d2e#diff-8cf16232f3b7094ea431234555d38ad71e6e62764c3e29a5841e25172aea5049R127-R130

Task:

• Figure out if we can avoid this...
