Reproduction of a problem with serverless functions

Check out /pages/api/hello.js.

• A font file is used by a SVG, which is located in /fonts/inconsolata.ttf
• There is a fonts/fonts.conf file specifying where to look for fonts
• An env variable is set like so: FONTCONFIG_PATH=/var/task/.next/server/chunks/fonts/
• The copy-webpack-plugin plugin is used and configured in next.config.js
• The fonts dir is in vercel.json in the includeFiles prop

What happens on the server

Upon the font not showing, it puts the following error into the log:

Fontconfig error: Cannot load default config file: No such file: (null)
