openclaw - 💡(How to fix) Fix web_search tool fails with 'fetch failed' despite valid Brave API key [1 participants]

The web_search tool consistently fails with fetch failed error, even though: 3. Observe fetch failed error in logs Actual: fetch failed with no detailed error message

Fix Plan

The fix involves modifying the web_search tool to properly use the OPENCLAW_WEB_PROXY environment variable for making requests to the Brave API.

Step-by-Step Solution:

1. Update web_search Tool: Modify the web_search tool to use a proxy agent when making requests.
2. Use https-proxy-agent Package: Install the https-proxy-agent package to handle proxying requests.
3. Implement Proxy in Code: Update the code to use the proxy agent when making requests to the Brave API.

Example Code:

const { HttpsProxyAgent } = require('https-proxy-agent');
const proxyUrl = process.env.OPENCLAW_WEB_PROXY;

// Create a new proxy agent
const agent = new HttpsProxyAgent(proxyUrl);

// Use the proxy agent when making requests
fetch('https://api.search.brave.com/res/v1/web/search?q=test&count=1', {
  headers: {
    'X-Subscription-Token': process.env.API_KEY
  },
  agent
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('fetch failed:', error));

Verification

To verify the fix, run the web_search tool again and check the logs for successful search results. You can also add additional logging to confirm that the proxy is being used correctly.

Extra Tips

• Ensure the OPENCLAW_WEB_PROXY environment variable is set correctly before running the web_search tool.
• If issues persist, try logging the proxyUrl variable to confirm it is being set correctly.
• Consider adding error handling to provide more detailed error messages in case of failures.
