Steps to reproduce

'gatsby build' and 'gatsby serve' used to work with gatsby V2 . Today , i ran npm install command to make sure that my packages are the latest. After this installation , gatsby build stopped working.

i have no issues with gatsby develop. Please find the error mentioned below.

Error: ./src/Containers/Sidebar/Sidebar.module.css
Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):
ModuleNotFoundError: Module not found: Error: Can't resolve 'Assets/fonts/Lato-Bold.ttf'

I have included the fonts path in my css files. This used to work before but stopped working now.

Expected result

gatsby build should work because it is used to work.

Actual result

gatsby build failed. I have pasted the error above.

The issue is introduced in 2.0.0-beta.37.

When i reverted to 2.0.0-beta.36 , the issue mentioned above is not seen.

Try upgrading to beta.38 which should have fixed this issue #6461
