Fix: Bruno Requests Not Showing in Proxyman

Hey guys, are you having trouble getting your Bruno requests to show up in Proxyman? You're not alone! This guide will walk you through troubleshooting steps to get Bruno and Proxyman playing nice together so you can debug your local API requests effectively. Let's dive in!

The Problem: Bruno Requests Missing in Proxyman

So, you're making requests to your localhost API using Bruno, and you expect to see those requests in Proxyman, but nothing shows up. You've even configured your /etc/hosts file to redirect localhost to proxyman.debug, and it works perfectly in Chrome. Bruno, however, seems to be sending the requests correctly (you're getting responses!), but Proxyman isn't picking them up. Frustrating, right?

Understanding the Setup

Before we get into the fixes, let's clarify the setup. You're essentially trying to route all traffic from your local machine through Proxyman, so you can inspect the HTTP requests and responses. This is super useful for debugging API calls and understanding what's happening under the hood. To achieve this, you've likely done the following:

  1. Configured /etc/hosts: You've added entries like 127.0.0.1 proxyman.debug and ::1 proxyman.debug to your /etc/hosts file. This tells your system to resolve proxyman.debug to your local machine.
  2. Using proxyman.debug in Chrome: When you use URLs like http://proxyman.debug:5001/ in Chrome, the browser correctly routes the traffic through Proxyman, and you can see the requests and responses in the Proxyman interface.
  3. Bruno Ignores Proxyman: When using Bruno, you get responses from your local API, indicating that Bruno is respecting some sort of proxy configuration. However, the requests are not visible in Proxyman.

Why This Happens

There could be several reasons why Bruno requests aren't showing up in Proxyman:

  • Proxy Settings in Bruno: Bruno might not be configured to use the system proxy settings correctly, or it might be overriding them with its own configuration.
  • SSL/TLS Issues: If your API is using HTTPS, there might be SSL/TLS certificate issues preventing Proxyman from intercepting the traffic. Proxyman needs to trust the SSL certificate to decrypt and display the traffic.
  • Incorrect Proxy Configuration: The system-wide proxy settings might not be correctly configured, or Bruno might not be picking them up.
  • Bruno Version Issues: Although unlikely, there could be specific bugs in the Bruno version you're using that prevent it from working correctly with Proxyman.

Solutions: Getting Bruno and Proxyman to Work Together

Alright, let's get down to business. Here are several solutions you can try to get Bruno requests showing up in Proxyman.

1. Verify System Proxy Settings

First, let's ensure your system proxy settings are correctly configured. Proxyman usually sets these up automatically, but it's worth double-checking.

  • macOS:
    1. Go to System Preferences > Network.
    2. Select your active network connection (e.g., Wi-Fi or Ethernet).
    3. Click Advanced...
    4. Go to the Proxies tab.
    5. Ensure that Web Proxy (HTTP) and Secure Web Proxy (HTTPS) are checked.
    6. The proxy server should be set to 127.0.0.1 and the port to 9090 (or whatever port Proxyman is using).

2. Configure Bruno to Use System Proxy

Next, make sure Bruno is configured to use the system proxy settings. Bruno might have its own proxy settings that are overriding the system settings. Check Bruno's settings to ensure it's set to use the system proxy.

3. Trust Proxyman's SSL Certificate

If your API uses HTTPS, Proxyman needs to trust its SSL certificate to intercept the traffic. If you haven't already, follow these steps:

  1. Install Proxyman Certificate:
    • In Proxyman, go to Certificate > Install Certificate on macOS > Install for This User.
  2. Trust the Certificate:
    • Open Keychain Access (search for it in Spotlight).
    • In the System keychain, find the Proxyman certificate.
    • Double-click the certificate.
    • Expand the Trust section.
    • Change "When using this certificate" to Always Trust.
    • Enter your password to save the changes.

4. Use Proxyman's Scripting Feature

You can use Proxyman's scripting feature to redirect requests from localhost to proxyman.debug. This can be particularly useful if Bruno doesn't fully respect the /etc/hosts file.

  1. Create a Script:
    • In Proxyman, go to Tools > Scripting.
    • Click the + button to add a new script.
    • Give the script a name (e.g., "Redirect Localhost").
  2. Add the Following Code:
function onRequest(context, request) {
  if (request.url.indexOf("localhost") > -1) {
    request.url = request.url.replace("localhost", "proxyman.debug");
    return request;
  }
  return null;
}
  1. Enable the Script:
    • Make sure the script is enabled in the Scripting window.

This script intercepts all requests and, if the URL contains localhost, it replaces it with proxyman.debug. This should force Bruno to route the traffic through Proxyman.

5. Check Bruno's Configuration Files

Sometimes, proxy settings can be embedded in Bruno's configuration files. Look for any .bru files or settings directories where Bruno stores its configurations. Check for any proxy-related settings and ensure they are either set to use the system proxy or are disabled.

6. Try a Different Port

In some cases, using a different port can resolve conflicts. Try changing the port your local API is running on and update the URL in Bruno accordingly. For example, instead of http://proxyman.debug:5001/, try http://proxyman.debug:6000/.

7. Update Bruno and Proxyman

Make sure you're using the latest versions of both Bruno and Proxyman. Outdated versions can sometimes have bugs that are resolved in newer releases. Check for updates in both applications and install them if available.

8. Restart Everything

It might sound simple, but restarting Bruno, Proxyman, and your local API can sometimes resolve unexpected issues. Close all the applications and start them again in the correct order: Proxyman first, then your API, and finally Bruno.

9. Use a Different HTTP Client

As a troubleshooting step, try using a different HTTP client (like Postman or Insomnia) with the same proxy settings. If the requests show up in Proxyman with a different client, it indicates that the issue is specific to Bruno. This can help you narrow down the problem and potentially find a workaround or report the issue to the Bruno developers.

Additional Tips for Debugging

  • Verbose Logging: Enable verbose logging in both Bruno and Proxyman (if available) to get more detailed information about what's happening with the requests.
  • Check Proxyman's Filters: Make sure you don't have any filters enabled in Proxyman that might be hiding the Bruno requests.
  • Use Proxyman's Breakpoints: Set breakpoints in Proxyman to intercept requests and inspect them before they're sent to the server. This can help you identify if the requests are being modified or redirected unexpectedly.

Conclusion

Getting Bruno and Proxyman to work together can be a bit tricky, but by following these steps, you should be able to get your requests showing up in Proxyman and debug your local API effectively. Remember to double-check your proxy settings, trust Proxyman's SSL certificate, and consider using Proxyman's scripting feature to redirect traffic. Good luck, and happy debugging!
