Diving into LaunchDarkly SDK Status Code 0 and Sentry Integration
Have you ever encountered a mysterious "LaunchDarkly SDK Status Code 0" while working with your application? This cryptic message can be frustrating, especially when it's coupled with a notification in your error monitoring system like Sentry.

Understanding LaunchDarkly SDK Status Code 0
LaunchDarkly SDK Status Code 0 is a signal that something went wrong during the communication between your application and the LaunchDarkly service. This code itself doesn't provide much specific information, but it's a crucial starting point for debugging.
Why Sentry Integration Matters

// Handle errors from the LaunchDarkly SDK
try {
// Your LaunchDarkly SDK operations
} catch (error) {
// If the error is related to LaunchDarkly SDK Status Code 0
if (error.message.includes('LaunchDarkly SDK Status Code 0')) {
