Error trying to connect from quarkus to keycloak

when starting up a quarkus service (v2.1.1), and trying to connect to a keycloak instance (v15.0.1) I am getting the following exception stack trace:

ERROR [io.qua.run.Application] (Quarkus Main Thread) Failed to start application (with profile dev): io.quarkus.oidc.common.runtime.OidcEndpointAccessException

Here are the configs I have put:

# OIDC Configuration
quarkus.oidc.auth-server-url=https://<HOST>/auth/realms/<REALM_NAME>
quarkus.oidc.client-id=<CLIENT_ID>
# quarkus.oidc.application-type=service
quarkus.oidc.credentials.secret=<SECRET>
quarkus.oidc.tls.verification=required

# Enable Policy Enforcement
quarkus.keycloak.policy-enforcer.enable=true

Anyone got an idea what's wrong here?

Thanks to a comment above I found this quarkus config here to be helpful:

quarkus.log.min-level=DEBUG
quarkus.log.category."io.quarkus.oidc".level=DEBUG

Which gave me this error:

Caused by: org.keycloak.authorization.client.util.HttpResponseException: Unexpected response from server: 400 / Bad Request / Response from server: {"error":"invalid_client","error_description":"Bearer-only not allowed"}

So clearly, I had misconfigured the client inside keycloak. Too bad the original error message didn't give me that information by default.
