Received "Unknown config option found" warning for enabling features from permanent feature list

Environment

self-hosted (https://develop.sentry.dev/self-hosted/)

What are you trying to accomplish?

I'm trying to enable (and hopefully implement) the uptime monitoring feature on self-hosted. Here I am trying to debug on the configuration for enabling it.

I saw the required feature flags in order to do so, with one of it being setting the organizations:uptime to True as seen here on the src/sentry/features/permanent.py file:

https://github.com/getsentry/sentry/blob/c6ee47d0bb20b5fe21a7ed8c31e70995ae1294ff/src/sentry/features/permanent.py#L109-L110

So, on Sentry server config, these are enabled:

SENTRY_FEATURES.update(
    {
        feature: True
        for feature in (
            # ... the original feature flags
        )
        # Uptime Monitoring related flags
        + (
            "organizations:uptime",
            "organizations:slack-threads-refactor-uptime", # Enable new slack threads logic for uptime issues
            "organizations:insights-uptime", # Enable access to insights uptime view
            "organizations:uptime-automatic-hostname-detection",
            "organizations:uptime-automatic-subscription-creation",
            "organizations:uptime-create-issues", # Enable creating issues via the issue platform
            "organizations:uptime-settings", # Enables uptime related settings for projects and orgs
            # Below these are for issues platform
            "organizations:uptime-domain-failure-visible",
            "organizations:uptime-domain-failure-ingest",
            "organizations:uptime-domain-failure-post-process-group",
        )
    }
)

Yet during the Sentry container startup, this line was emitted from the log:

* Unknown config option found: 'uptime'

How are you getting stuck?

Then I try to debug this further by executing the Django shell inside the Docker container like so:

docker compose --env-file .env --env-file .env.custom exec web /etc/sentry/entrypoint.sh shell -c "from sentry.features import default_manager
print(default_manager.has(\"organizations:uptime\"))
"

This is the output:

Updating certificates in /etc/ssl/certs...
0 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...
done.
[WARN  tini (29992)] Tini is not running as PID 1 and isn't registered as a child subreaper.
Zombie processes will not be re-parented to Tini, so zombie reaping won't work.
To fix the problem, use the -s option or set the environment variable TINI_SUBREAPER to register Tini as a child subreaper, or run Tini as PID 1.
* Unknown config option found: 'uptime'
False

Executing this on Django shell returns True:

docker compose --env-file .env --env-file .env.custom exec web /etc/sentry/entrypoint.sh shell -c "from django.conf import settings
print(settings.SENTRY_FEATURES[\"organizations:uptime\"])
"

Am I doing this wrong? Or is this a bug from the sentry code?

Where in the product are you?
