gatsby-3-static-query-issue

Reproduction of the issue with useStaticQuery in Gatsby 3 + Nelify CMS setup

How to reproduce:

1. npm ci - installing dependencies
2. npm run develop - running the dev server
3. Go to http://localhost:8000, you should see a modal box with the error message Unhandled Runtime Error

Now if you go to the src/pages/index.ts file and change something, after refreshing the page error should disappear (but it will be back at some point).

Tested on this setup:

• Node.js: v14.15.0
• NPM: v6.14.11
• OS: Mac OS Big Sur
• Browser: Google Chrome
