Describe the bug
Hi.
We've recently updated our keycloak to 18.0.0. Everything worked fine, automatically, except the logout mechanism. Our site was still using redirect_uri. We updated the frontend to use the most recent keycloak-js. Now it is sending post_logout_redirect_uri and id_token_hint correctly.
And here is the issue, the logout is resulted in a Server Error: 404 " 404 - File or directory not found. The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable. "
I read that the 18 keycloak now asks confirmation to logout. We are using a custom template for the client. Do we miss the page for the logout confirmation from our template? If so, where can I find a sample template for this?
Would be nice: to display the error message in the log, what is not found exactly.
Cheers, Ádám
