Describe your problem

When I was using the Agent, I wanna turn on the internet search: TavilySearch. But after I configured the API KEY and did a trial run, it gave an error. The error message is like this: TypeError("'NoneType' object is not subscriptable")

Hi @1430340687! I'm Dosu and I’m helping the ragflow team.

This error usually means the TavilySearch agent tried to access a field in the API response, but the response was None—often because of a missing or invalid API key, or a failed/malformed response from Tavily. In the code, if the Tavily API key is missing or incorrect, the search call can silently fail and return None, which then triggers the TypeError when the code tries to access res["results"] or similar fields see code reference.

Here’s what you can check:

• Make sure the API key is correctly set in the UI and is valid (no extra spaces, not expired, and has the right permissions).
• If you recently upgraded or changed how you enter the API key, note that the UI and backend handling of API keys was recently refactored—try re-entering the key and saving the agent again see PR #9086.
• If you’re not using the latest (nightly) version, try upgrading—several TavilySearch and API key issues are resolved in the nightly Docker image see issue #6583.
• If the error persists, check the logs for any Tavily-related errors or exceptions, which might give more detail about what’s going wrong.

This pattern of error is not unique to TavilySearch—similar issues happen elsewhere in RAGFlow when an external API response is None and the code doesn’t check for it before subscripting see related issues. Defensive checks and clearer error messages are being improved, but for now, double-checking your API key and version is the best first step.

To reply, just mention @dosu.
