Laravel Mix rule.loader problem after migrating site to new server

I created a new server and want to migrate my existing laravel application to it.

I got the database cloned and I used git to clone the source files.

I ran composer install and then npm install. Npm install took a few runs plus some audit fix passes, but eventually seemed to complete successfully after I installed cross-env and webpack.

Now, it is giving me a rule.load.find( is not defined error.
