Unable to authenticate quarkus application to keycloak

[hervé Fokher]

I trying to secure java application with quarkus framework

Materials: Keycloak 22

Jdk 22

For protecting server-side web applications, we will use a mywebapp client:
• Client ID: mywebapp
• Client authentication: ON
• Root URL: http://localhost:8080
• Valid Redirect URI: /*

the configuration of quarkus where all is the same in my keycloak server:

In keycloak, config of client:

Please I didn't succeed to authenticate my application to keycloak after I enter the credential to login page of keycloak:

I have this page after authenticate 

username: alice, password:alice.

The root cause of the error is that Keycloak indicates that the client credentials provided by my Quarkus application are invalid, instaeda  all is the same like you see the pictures

I will be happy with your contribution please. 

Thank you
