Hello, We have translated keycloak into multiple languages, available at [1]. I've copied those translations into our custom theme and build the docker image. I updated the iimage and it fails to start with the following exception. Just the files being there causes the above exception. Any ideas how to fix this ? Regards, ``` 15:47:17,655 ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-6) Failed to create error page: java.lang.NullPointerException     at
