📷 错误截图

Start with media_platform/xhs/core.py and proxy_ip_pool.py, then reproduce the command shown in the report and inspect the Playwright Page.goto failure. Verify how the proxy is validated and passed to the browser context; done means the Xiaohongshu page loads successfully with the configured proxy and the failure is covered by a clear diagnostic or test.
