Time out during "Waiting for framework port" when index results in 404

[tomlschmidt]

Describe the bug

My Gatsby page doesn't have a page at index, which seems for the CLI to not notice when the framework port becomes available using the dev command. As soon as I add an index.js, the CLI works as intended.

Steps to reproduce

1. Create a new Gatsby site
2. Remove the index.js file
3. Start the Netlify dev server using netlify dev
4. See that "Waiting for framework port 8000" message is being shown even when the Gatsby development server is already available at "localhost:8000"
5. Add an index.js file and see that the CLI works as intended
