Cannot config APPLICATION_ROOT and STATIC_ASSETS_PREFIX

[ratthapon]

I'm try to deploy Superset behind nginx proxy.
Already setup nginx to redirect hostname.tld/analytics -> service:port with required headers.

Superset is working except:

1. static asset prefix didn't change.
2. only user_info menu doesn't have url prefix, other menus are looking good.

I'm try to change these config in superset_config.py but it doesn't work.

configOverrides:
    proxy: |
        ENABLE_PROXY_FIX = True
        APPLICATION_ROOT = "/analytics"
        STATIC_ASSETS_PREFIX = "/analytics"

I'm deploy using helm 0.15.0 and image version 6.0.0.

Superset’s subpath deployment (using APPLICATION_ROOT and STATIC_ASSETS_PREFIX) is still BETA in 6.0.0 and has some known gaps. The static asset prefix often doesn’t apply everywhere, and the user_info menu URL is hardcoded without the prefix—these are recognized issues and not fully fixed in your version [source].

For best results, set the environment variable SUPERSET_APP_ROOT to /analytics in your Helm values (not just in superset_config.py), and let Superset auto-populate APPLICATION_ROOT and STATIC_ASSETS_PREFIX. Also, set ENABLE_PROXY_FIX = True and PROXY_FIX_CONFIG = {"x_for": 1, "x_proto": 1, "x_host": 1, "x_port": 1, "x_prefix": 1} to ensure Superset trusts the X-Forwarded-Prefix header from nginx. Your nginx config should set proxy_set_header X-Forwarded-Prefix /analytics; [source].

The missing prefix in user_info is a known bug; the only workaround is to rewrite /user_info/ to /analytics/user_info/ at the proxy or with custom middleware until a newer Superset release lands with a fix [source]. Static assets may also need explicit proxy rules for /analytics/static/ [source].

After changing config, clear your browser cache to avoid stale bootstrap data causing broken links. If you need more robust subpath support, consider upgrading to a release after late 2025 or using a subdomain instead of a subpath [source].

Let me know if you want example Helm values or nginx config for this setup.
