[keycloak-user] keycloak.js updateToken does not validate refresh token expiration date

keycloak.js updateToken does not validate refresh token expiration date in example https://github.com/keycloak/keycloak/blob/master/examples/demo-template/a... when i call getToken() method after refresh token expires i get console.info('[KEYCLOAK] Refreshing token: token expired'); from keycloak.js:400 with /auth/realms/InfiniteBirEUmowy/protocol/openid-connect/token 400 (Bad Request) [KEYCLOAK] Failed to refresh token I need to check if refresh token does not expired and if it is call KeycloakService.auth.authz.login(); Why this token refresh expiration check is not handled by updateToken inside keycloak.js updateToken()?
