-## Verify

-```JavaScript
-import * as Sentry from '@sentry/browser';
-import * as LaunchDarkly from 'launchdarkly-js-client-sdk';
-
-// Evaluate a flag with a default value, with the ldClient from the Configure step.
-// You may have to wait for your client to initialize before doing this.
-ldClient?.variation("hello", false);

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