## The problem
Issue launchdarkly/js-core#568 (closed, 14 comments): **Describe the bug** The example provided in the README.md is not working **To reproduce** ```ts import { init } from '@launchdarkly/node-server-sdk'; import { RedisFeatureStore } from '@launchdarkly/node-server-sdk-redis'; (async function main() { const client = init(process.env.LD_KEY!, { featureStore: RedisFeatureStore(), }); await client.waitForInitialization({ timeout: 5 }); })();
## What fixed it
[kinyoklion (maintainer)]: Fixed in @launchdarkly/node-server-sdk 9.5.4. If the README redis example fails (waitForInitialization timing out with RedisFeatureStore), upgrade the SDK to 9.5.4 or newer.
