JavaScript SDK HTTP Errors

Error Message

 Description

413 HTTP error code

1. Consider reducing the size of the context object passed to the SDK:
   • Limit the number of attributes and nested data structures.
   • Aim for the object to be under 1481 characters, accounting for base64 encoding.
2. Use the useReport option in the SDK configuration:
   • This places the context in the body of the HTTP request instead of the URL.
   • Note: Enabling useReport results in slower SDK performance because it bypasses edge caching and requires direct communication with LaunchDarkly.
3. Ensure compatibility with streaming by using the LaunchDarkly Requirements and polyfills.
4. If your client-side connections are going through a reverse proxy or a load balancer, then ensure the limits on traffic size are sufficient.  

1. Verify the network configuration to ensure long-lived connections are allowed.
2. Address potential network disruptions or browser policies that might terminate connections unexpectedly.
