Flag removed from code is still showing evaluations

Affected: All SDKs

Symptoms

• A flag removed from the codebase is still showing evaluations.

Cause

• If this flag is not using a JS-based SDK: A variation call with the explicit name of the flag is being called.

• If this flag is using a JS-based SDK: The JS SDK (and JS-based SDKs, such as React versions 2.26 and earlier) is making an allFlags call (or useFlags hook in React SDK) to get flag values for all flags available to client-side SDKs in the specified environment. The allFlags method will send a feature event to LD. This would be the equivalent of calling variation for every flag. 

Solution

For non-JS-based SDKs:

1. Search the flag name in any non-main codebase in testing or isolated machines.

For JS-based SDKs:

1. Make the flag unavailable to client-side SDKs in the flag Settings tab.

2. Configure sendEventsOnlyForVariation to true in the client-side SDK. When this option is set to true, analytics events will only be sent when variation is called. To configure this option, reference sendEventsOnlyForVariation.

3. If there are still evaluations, search for the flag name in any non-main codebase.
