Can't get Keycloak with Nuxt.js (and Vert.x to run) / CORS

1

Here’s my branch:

Now I’m having trouble with Chrome, Keycloak and CORS. It says that Origin null is not allowed, but “Web Origins” in Keycloak is set to http://127.0.0.1. Plus Chrome doesn’t let me set the Origin with the Axios HTTP-header.
