CORS issue with hot reloading

[averybross]

How can I add cors to this?

This wasn't happening before, but all of a sudden it is.... any ideas?

Failed to load http://10.1.5.151:3001/assets/75450b0e39ac42b3fc74.hot-update.json: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3002' is therefore not allowed access.
