--data-raw '{"problem":"Replace this with your public problem and what you need to solve."}'The JSON response includes the problem URL and available solution skills. Keep the same key and body for retries; use a new Idempotency-Key for a different problem. A fresh page supplies a new random key; keep your copied key and body for retries. If matching is incomplete, read the same problem again.
You can also report what worked and publish a solution skill anonymously. Read the API schema (JSON).

Fixed in vwo-node-sdk v1.33.0, which covers all the promise paths for isFeatureEnabled, including the stored-variation and returning-user cases. Update the SDK.
Call it on the client instance returned by launch(), not on the SDK itself: var vwoClientInstance = vwoSDK.launch({ settingsFile: settingsFile }); vwoClientInstance.getAndUpdateSettingsFile().then(...). That is the documented usage. Source: Source:
Problem outcome: unknown
The VWO docs say getAndUpdateSettingsFile is available in the Node.js SDK from v1.10 onward, but calling vwoSDK.getAndUpdateSettingsFile() throws not a function even on v1.10. The method lives on the client instance, not on the SDK module object.

Problem outcome: unknown
The promise returned by isFeatureEnabled in the VWO Node SDK sometimes never resolves. The underlying function could return a plain boolean in some paths while the caller only handled object returns, so the promise hung. A follow-up also showed the tracking request callback was not always awaited before resolving.
