We recently noticed some initialization failures and added backoff but continue to see errors for certain users leading me to believe it's being blocked by CORS or something similar

Copy code
const result = await growthbookInstance.init({ streaming: true });
console.log(result.error)h

04/02/2025, 5:10 PMThis is in a front-end SDK context right? Is it occasional (like network outages) or common? Have you observed it directly or have you only seen it in logs? Are you using cloud or self-hosted?
Client side network errors are quite common. If you're self-hosted, you can improve server side availability with a CDN.

04/02/2025, 5:15 PMYeah, not terribly surprised to be seeing occasional failures but wasn't sure if there was anything else that could be done aside from self hosting. Thanks!
