GitHub user dosubot[bot] added a comment to the discussion: Attribute not found error in superset_config.py
<!-- Answer --> No, using FAB_INDEX_VIEW to set a custom IndexView in Superset 5.x does not work—this config is ignored and always results in the AttributeError you saw, even if your class is defined correctly. This is a breaking change: Superset 5.x only supports customizing the IndexView via FLASK_APP_MUTATOR, not FAB_INDEX_VIEW. There are no exceptions or workarounds for this in 5.x ([details](https://github.com/apache/superset/issues/34441), [discussion](https://github.com/apache/superset/discussions/34530), [issue](https://github.com/apache/superset/issues/34422)). To customize the IndexView, define your custom class and set appbuilder.indexview inside a mutate_app function, then assign that function to FLASK_APP_MUTATOR in your config: ```python from flask_appbuilder import expose, IndexView from superset.typing import FlaskResponse class SupersetDashboardIndexView(IndexView): @expose("/") def index(self) -> FlaskResponse: return redirect("/dashboard/list/") def mutate_app(app): from superset.extensions import appbuilder appbuilder.indexview = SupersetDashboardIndexView FLASK_APP_MUTATOR = mutate_app ``` Remove any FAB_INDEX_VIEW lines from your config. If you’re using Docker Compose, put your config at `/app/docker/pythonpath_dev/superset_config_docker.py` and restart your containers so it’s picked up. If you still see errors, check your logs for syntax or import errors in your config file—any such error will prevent your class from being available ([source](https://github.com/apache/superset/issues/34441)). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
