This integration only works inside a browser environment. It is only available from a package-based install (e.g. npm or yarn).

Flagsmith relies on the OpenFeature integration to track feature flag evaluations produced by the OpenFeature SDK. These evaluations are held in memory, and in the event an error occurs, sent to Sentry for review and analysis. At the moment, we only support boolean flag evaluations. This integration is available in Sentry SDK versions 8.43.0 or higher.

Import name: Sentry.openFeatureIntegration and Sentry.OpenFeatureIntegrationHook

Visit the Sentry website and confirm that your error event has recorded the feature flag "test-flag" and its value "false".
