404 Page Doesn't Build

[joshuabradley012]

Environment: node 8.17.0, npm 6.13.6, hugo 0.62.1

When a 404.html page is created in /site/layouts, running npm run build creates a dist without the 404.html file.

It fails specifically at npm run build:hugo which is included in the npm run build command.

However, manually running the command that npm run build:hugo is firing works. Meaning hugo -d ../dist -s site -v generates the 404 page properly.
