webpack 5.74.0 compiled with 5 errors in 24868 ms

webpack seems to try to make some more progress after this but then hangs forever after hitting some warnings:

WARNING in entrypoint size limit: The following entrypoint(s) combined asset size exceeds the recommended limit (244 KiB). This can impact web performance.
Entrypoints:
  veApp (6.97 MiB)
      js/veApp.bundle.js

WARNING in webpack performance recommendations: 
You can limit the size of your bundles by using import() or require.ensure to lazy load some parts of your application.

I'm not very familiar with webpack. I found this:

https://stackoverflow.com/questions/53885107/typescript-cant-find-module-flatpickr-even-though-it-includes-typescript-types

but their suggestion of setting "moduleResolution": "node" already seems to be set in tsconfig.json.
