Keycloak exception: Cannot invoke "Object.toString()" because the return value of "io.vertx.core.http.HttpServerRequest.authority()" is null

Установил локально Keycloak, делаю все как по гайду: создал realm "test-realm", в нем клиента "test-client" и пользователя "user1" с паролем 123456.
При обращении по эндпоинту для получения токена (http://localhost:8180/realms/test-realm/protocol/openid-connect/token) поулчаю ошибку
