Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Git Clone

Open WebUI Version

0.6.10

Ollama Version (if applicable)

No response

Operating System

macOS sequoia

Browser (if applicable)

Chrome

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have listed steps to reproduce the bug in detail.

Expected Behavior

When the web search function encounters an error while fetching content from a website:

  1. The error message should contain detailed information about what went wrong
  2. Users should be able to see meaningful error details to understand why the fetch failed
  3. The system should provide actionable information (e.g., "403 Forbidden", "Connection timeout", etc.)

Actual Behavior

The web search function shows a warning with an empty error object when failing to fetch content from Tesla.cn:

  • Error message ends with - {} (empty object)
  • No meaningful error details are provided
  • Users cannot understand why the request failed

Steps to Reproduce

  1. Open Open WebUI interface
  2. Ask a question that would trigger web search for Tesla news (e.g., "最近特斯拉的新闻有没有")
  3. Observe the system attempting to fetch from https://www.tesla.cn/blog
  4. Check the logs for the warning message
  5. Note that the error object is empty: - {}

Logs & Screenshots

2025-05-25 02:29:43.906 | WARNING | langchain_community.document_loaders.web_base:_fetch_with_rate_limit:271 - Error fetching https://www.tesla.cn/blog,⁠ skipping due to continue_on_failure=True - {}

Additional Information

  • This appears to be related to the langchain_community.document_loaders.web_base module
  • The continue_on_failure=True setting causes the system to skip failed URLs silently
  • This makes debugging web search issues difficult for users and administrators
  • Suggested improvement: Capture and log the actual exception details instead of an empty object

This functionality is provided by langchain_community, the web loader won't log out error messages when continue on failure is set. Maybe consider creating an issue under langchain project? Or just re-implement the web loader.

此功能由 langchain_community 提供，当设置了“失败时继续”时，Web 加载器不会输出错误消息。或许可以考虑在 langchain 项目下创建一个问题？或者干脆重新实现 Web 加载器。

Thanks, my search function doesn't work now

#14029 #14073 Already fixed in dev, for now just disable ssl validation to avoid the error

or just adjust value of WEB_SEARCH_CONCURRENT_REQUESTS env var.
langchain_community.document_loaders.web_base lib is used on web scrap ( 82716f3789/backend/open_webui/retrieval/web/utils.py ) & it have a parameter(RateLimitMixin) that is dynamically setted based on that env var (82716f3789/backend/open_webui/routers/retrieval.py (L1368) )
