Java SpringBoot Keycloak Rest Api Jwt Auth Postman Didn't find publicKey for kid - spring-boot

Question

I'm creating a microservices project. The idea is that a reactjs application get a token from Keycloack and send this jwt token to a springboot rest api in the backend. I'm using docker compose to manage the containers in my local machine.
With Postman I get the token form keycloack, but when I use this token as bearer token to call the rest api with Postman,I'm getting 401.
I configured keycloak, but in the backend, in the logs I found the error:
2021-02-28 10:37:14.134 ERROR 1 --- [nio-8081-exec-4] o.k.a.rotation.AdapterTokenVerifier : Didn't find publicKey for kid: fbb8f5e8-2341-4d1d-82d8-6efe736c90c5
In the logs of keycloak I see:
10:22:19,590 INFO [org.keycloak.keys.DefaultKeyManager] (default task-4) No keys found for realm=master and algorithm=HS256 for use=SIG. Generating keys.
10:22:25,423 INFO [org.keycloak.keys.DefaultKeyManager] (default task-5) No keys found for realm=master and algorithm=RS256 for use=SIG. Generating keys.
10:23:18,927 WARN [org.keycloak.events] (default task-4) type=LOGIN_ERROR, realmId=todo-realm, clientId=todo-app, userId=null, ipAddress=172.29.0.1, error=invalid_client_credentials, grant_type=password
In the Springboot application.properties i put these properties:
keycloak.realm = todo-realm
keycloak.auth-server-url = http://keycloak:8080/auth
keycloak.ssl-required = external
keycloak.resource = todo-app
keycloak.credentials.secret = the secret of the client in keycloack
keycloak.use-resource-role-mappings = true
keycloak.bearer-only = true
In the keycloak I created a realm called: todo-realm. I created a client called todo-app and two roles:
app-user
app-admin
I creted a user, called user1, with the role: app-user.
In my springboot app, the pom is:

I created a class to configure keycloack:

super.configure(http);
http.authorizeRequests()

.antMatchers("/api/todo/delete").hasAnyRole("user")
.antMatchers("/api/todo/delete/{id}").hasAnyRole("user")*/
.anyRequest()
.permitAll();
http.csrf().disable();
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(new SimpleAuthorityMapper());
auth.authenticationProvider(keycloakAuthenticationProvider);
}

Can someone help me to get the result of the rest api using Postaman of my rest api ?
Thank you so much.
