JavaScript SDK HTTP Errors

 Description

413 HTTP error code

1. Reduce the size of the context object passed to the SDK.
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.

414 HTTP error code

The error occurs during SDK initialization when the context object exceeds browser URL size limitations.

1. Reduce the size of the JSON context object:
   • Limit the number of attributes and nested data structures.
   • Aim for the object to be under 1481 characters, accounting for base64 encoding.
2. Consider using the server-side SDK or other methods that do not depend on URL-based transmission for large payloads.

Error on stream connection: {"isTrusted":true}, will continue retrying every 1000 milliseconds

The message {"isTrusted":true} 
appears when the streaming connection ends unexpectedly.

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.

XHR Errors in Older SDK Versions

These errors may appear if an end user closes a page.

Update the SDK to version 3.1.4 or later. This resolves known issues related to page closures.
