Exception with Eureka client Expected authority at index 7: http:// - spring-boot

Question

Why can I get this error when I call my controller appending the URL:
http://127.0.0.1:8080/status/tenant_1 to my browser?
I want to call an Eureka service client called saf.

This is my controller (but when debugging is on, there are no break point it just stops:

Where saf in http link is the service discovered by Eureka Server:
Registered instance SAF/MYHOST.MYDOMAIN.it:saf:8090 with status UP (replication=false)
Like in the bootstrap.yml configuration file:
spring:
application:
name: saf
Aand in the application.properties (eureka server listen on port 8761):

Answer 1

Managed to get it work appending any authority in feign client interface
#FeignClient("avantgarde-crm#avantgarde-security")
interface AuthenticationClient {
#PostMapping
fun authenticate(#RequestBody request: AuthenticationRequest): Token
#GetMapping
fun authentication(#RequestHeader(HttpHeaders.AUTHORIZATION) token: String): Authentication
}

spring-cloud-starter-netflix-ribbon 2.0.0.M7
spring-cloud-starter-openfeign 2.0.0.M1

Answer 2

This is because the path of the URL is missing. In the rare case that you want to request the root path (no /resource/1234 etc part of the url), you can use #GetMapping("/") etc.
