[www] Running gatsby develop on www directory of Gatsby repo fails.

Description

I am trying to contribute to Gatsby and followed the steps show in the website (twice). Both the times yarn test failed with exit code 1 ( see #21473 ) so I started working on the www directory straight away. But I can't run gatsby develop because of some error.

Steps to reproduce

Fork the repo
yarn run bootstrap
yarn test (fails with exit code 1)
Go to www directory and yarn install
gatsby develop

Expected result

Development server should start successfully.

Actual result

Go this error instead:

success open and validate gatsby-configs - 2.739s
success load plugins - 22.774s
success onPreInit - 0.144s
success initialize cache - 1.107s
success copy gatsby files - 0.347s
success onPreBootstrap - 0.086s
success createSchemaCustomization - 0.743s
