Research direction

Start by reproducing the difference in the Requestly Desktop App using the listed proxy, curl/browser requests, and the Requestly-initiated request. Compare why the intercepted 500 response appears but the request is absent from the list; done means the Requestly request is recorded while the existing interception rule still works.

Describe your issue?

I have a simple Express app on localhost:3000/httpbin that hits httpbin.org

// Third-party API call to httpbin
app.get('/httpbin', async (req, res) => {
  try {
    const response = await axios.get('https://httpbin.org/get');
    res.json(response.data);
  } catch (error) {
    res.status(500).json({ error: 'Failed to fetch from httpbin', details: error.message });
  }
});

I'm trying to intercept this call and replace it with a 500 response. I have set up the proxy in my terminal where the app is running. I have the rule set up.

If I do curl localhost:3000/httpbin, I can see it works.

However, if I hit the same endpoint through Requestly, the rule still works (because I can see 500 error), but it doesn't show up in the list.

I'm extremely confused. Both are making requests to localhost:3000/httpbin, so why is one showing up and not the other? I can also open localhost:3000/httpbin on my browser and it also records the URL.

Repro steps
  1. Set up proxy.
  2. Run npm start
  3. Make request via curl or browser - works
  4. Make request via Requestly - does not work.
