Web UI NOT FOUND

[KevinGe00]

Hi @Yiutto, the backend and UI run on different ports on localhost. The Spring service you have running is strictly the backend, which you can access using the CLI with instructions here.

The UI must be spun up separately using instructions here, the UI will be (by default) run on http://localhost:3000/. Please note that the instructions here are missing a step where you must cd into https://github.com/linkedin/coral/tree/master/coral-service/frontend and run npm install before running npm run dev. Please let me know if you have further questions.
