🐛 Bug Report: ClickHouse expiration days isn't configurable

[michislava]

📜 Description

We wanted to reduce the number of LOG_EXPIRATION_DAYS_NUMBER to 30. So we passed it as an env var in the deployment of our api and worker pod.

But we got the following error in both pods:

[Nest] 1  - 01/13/2026, 1:46:09 PM     LOG [EnterpriseProvider] Using noop SendWebhookMessage provider
================================
 Invalid environment variables:
    LOG_EXPIRATION_DAYS_NUMBER: Invalid bool input: "30"
================================
 Exiting with error code 1

So it seems that this value isn't configurable since it is bool.

Here in v.3.11.0 we see that when an exception is thrown, a warning log is displayed and it again falls back to 100 days:

} catch (error) {
      this.logger.warn(
        { error: error instanceof Error ? error.message : 'Unknown error' },
        'Failed to fetch log expiration days from LaunchDarkly, falling back to 100 days'
      );

return addDays(new Date(), 100);

Can we make this env var: LOG_EXPIRATION_DAYS_NUMBER configurable?

👟 Reproduction steps

Try to pass this env var name: LOG_EXPIRATION_DAYS_NUMBER to override default settings.

👍 Expected behavior

    - name: LOG_EXPIRATION_DAYS_NUMBER
      value: "30"

This to work correctly and we override the 100 days expiration with 30 days.

👎 Actual Behavior with Screenshots

}
[Nest] 1  - 01/13/2026, 1:46:09 PM     LOG [EnterpriseProvider] Using noop SendWebhookMessage provider
================================
 Invalid environment variables:
    LOG_EXPIRATION_DAYS_NUMBER: Invalid bool input: "30"
================================
 Exiting with error code 1

This isn't configurable.
