Sentry Not Logging Errors for Some Clients in React App? Here’s What You Need to Do

If you’re a React developer, chances are you’ve encountered the frustration of Sentry not logging errors for some clients in your application. You’ve set up Sentry, implemented error tracking, and yet, some errors seem to slip through the cracks. What’s going on?! In this article, we’ll dive into the common culprits behind this issue and provide a step-by-step guide to ensure that Sentry logs errors for all your clients.

Understanding Sentry and Error Tracking in React

Sentry is a popular error tracking tool that helps developers identify and fix errors in their applications. In a React app, you’d typically set up Sentry by installing the `@sentry/react` package and wrapping your app with the Sentry error boundary. This allows Sentry to capture and report errors that occur in your application.

import { withProfiler } from '@sentry/react';
import { Integrations } from '@sentry/tracing';
import * as Sentry from '@sentry/react';

Sentry.init({
  dsn: 'https://@sentry.io/',
  integrations: [new Integrations.BrowserTracing()],
  tracesSampleRate: 1.0,
});

Why Sentry Might Not Be Logging Errors for Some Clients

Before we dive into the solutions, let’s explore some common reasons why Sentry might not be logging errors for some clients:

• Incorrect Sentry setup: If Sentry is not properly set up or initialized, it won’t log errors.
• Browser or device issues: Certain browsers or devices might have issues with JavaScript or HTTP requests, preventing Sentry from logging errors.
• Network connectivity problems: If a client’s network connection is unstable or slow, Sentry might not receive error reports.
• Error handling and suppression: If errors are being caught and handled within your application, Sentry might not receive error reports.
• Sentry rate limiting: If you’re exceeding Sentry’s rate limits, error reports might not be processed.

Troubleshooting and Solution

Now that we’ve covered the common culprits, let’s work through a step-by-step guide to troubleshoot and resolve the issue:

Step 1: Verify Sentry Setup and Configuration

Double-check your Sentry setup and configuration:

1. Ensure you’ve installed the correct Sentry package for your React app (`@sentry/react`).
2. Verify your Sentry DSN is correct and properly configured.
3. Check that Sentry is initialized and wrapped around your app.

import * as Sentry from '@sentry/react';

Sentry.init({
  dsn: 'https://@sentry.io/',
  // ...
});

function App() {
  return (
    <Sentry.ErrorBoundary>
      <YourApp/>
    </Sentry.ErrorBoundary>
  );
}

Step 2: Check Browser and Device Compatibility

Test your application on different browsers and devices to identify potential issues:

• Test on popular browsers like Chrome, Firefox, Safari, and Edge.
• Test on different devices, such as desktops, laptops, mobile devices, and tablets.

Step 3: Review Network Connectivity and Request Headers

Investigate network connectivity and request headers:

1. Check the network requests in your browser’s developer tools to ensure that Sentry requests are being sent.
2. Verify that the `Content-Type` header is set to `application/json` in your Sentry requests.

// Example Sentry request headers
Content-Type: application/json
X-Sentry-Auth: Bearer 

Step 4: Identify Error Handling and Suppression

Analyze your application’s error handling and suppression mechanisms:

• Search for `try-catch` blocks or error handling functions that might be suppressing errors.
• Check if any error-handling libraries or middleware are interfering with Sentry.

try {
  // Code that might throw an error
} catch (error) {
  // Error handling or suppression might occur here
  console.error(error);
}

Step 5: Review Sentry Rate Limits

Verify that you’re not exceeding Sentry’s rate limits:

• Check your Sentry plan and rate limits.
• Implement strategies to reduce the number of error reports, such as error aggregation or sampling.

// Example Sentry rate limit response
HTTP/1.1 429 Too Many Requests
RateLimit-Remaining: 0
RateLimit-Reset: 1643723400

Additional Tips and Best Practices

To ensure that Sentry logs errors for all your clients, follow these best practices:

TIP	DESCRIPTION
Use a Sentry error boundary	Wrap your app with a Sentry error boundary to catch and report errors.
Implement error reporting for all errors	Report all errors, including handled and unhandled errors, to Sentry.
Use Sentry’s built-in integrations	Take advantage of Sentry’s integrations with popular libraries and frameworks to provide more context and detail.
Monitor Sentry performance	Regularly monitor Sentry performance and adjust your setup as needed.

Conclusion
