Using Nuxtjs/fonts broke Netlify Build

[mayashavin]

Steps to re-produce

1. Add Nuxtjs/fonts to existing Nuxtjs project.
2. Commit and merge to repo.
3. Netlify CI to run the build automatically

Expected: It should work and deploy new website.
Actual: Build failed due to stack overflow (see below)

  },

It works locally, only fails in deployment. I tried to build locally but I got error on the pre-render sitemap thing, not the stack overflow error.
Removing prerender and build locally works (not sure if this relates).

[danielroe]

does it work locally / in production if you only remove the sitemap from being prerendered?

any chance you have a minimal (or any) reproduction?

I've run into a similar problem before with my own project. I don't think it's a problem with Fonts - the OOM happens in the functions bundling stage so the problem should be on Netlify's side. Please refer to this for more info.
