KeyCloak and Quarkus can't start in dev mode

Question

Hello I am currently trying to do this tutorial : https://quarkus.io/guides/security-keycloak-authorization

But when I run quarkus dev I get this error.

ERROR [io.qua.run.Application] (Quarkus Main Thread) Failed to start application (with profile dev): java.util.NoSuchElementException: No value present

I did everything as intended in the tutorial

until starting the Quarkus project in dev mode.
