I found a problem to start App Builder into a local env

just:

  • clone release/v7.3.0 (5f9cab6)
  • npm install and start

and request http://localhost:3000/ loops forever with console error
Warning: Invalid argument supplied to oneOfType. Expected an array of check functions, but received undefined at index 1. at AppTour.js:539
