My `FnRetrieverOpenAIAgent from

At a glance

The community member is experiencing an error with their FnRetrieverOpenAIAgent.from_retriever() function, which was previously working but now throws an exception: "There is no current event loop in thread 'Thread-1'". They have tried upgrading the llama-index package to version 0.8.4, but the issue persists. The community members discuss potential causes, such as the code changes in the newer version, and suggest trying older versions. However, the issue seems to be related to the tool's behavior rather than the package version. The community members are unable to identify a clear solution and suggest reproducing the issue locally to debug further.

was working until recently, now I'm getting the following error:

Any ideas what could have went wrong during update ? Thanks a lot

what llama-index version do you have?

ccordbob

I have 0.8.3 installed

LLogan M

hmm can you try 0.8.4?

ccordbob

From 0.7.24.post1 I get the error:

ccordbob

I tried 0.8.4 but still got the error so I started downgrading until last working package, I should update more frequently 🫠

LLogan M

That error isn't possible in 0.8.4, that specific line of code has changed 👀

The traceback still has the old version of code?

ccordbob

I restore the virtual environment, now the exception is no longer showed up during start up.
The exception occurs after "Tool description"

It should go like:

...
Tool description: get_location_information(address: str, cate...
DEBUG:openai:message='Request to OpenAI API' method=post path=https://api.openai.com/v1/chat/completions

Why would it not Request to OpenAI API?

LLogan M

well, it's not requesting because something about the tool is barfing, I still see that event loop issue 🤔 I'll have to reproduce this locally to debug properly
