langfuse_filter_pipeline.py 'str' object has no attribute 'get'

[sao-coding]

langfuse_filter_pipeline.py is error

'str' object has no attribute 'get'

This is a workaround, I have a self-hosted LangFuse instance and was running into the same error in the UI and in my docker container.

I uploaded this .py to open-webui and replaced it in the pipelines container folder as well: https://github.com/karaketir16/openwebui-langfuse/blob/master/example/langfuse_filter_pipeline.py

This is not an issue that we see across integrations, happy to help with resolution of this issue.

I got the same issue with latest pipelines using the v1.3 found here https://raw.githubusercontent.com/open-webui/pipelines/refs/heads/main/examples/filters/langfuse_filter_pipeline.py

it seems that the workaround is aiming at older version of the filter v1.1 https://raw.githubusercontent.com/karaketir16/openwebui-langfuse/refs/heads/master/example/langfuse_filter_pipeline.py

what ever was posted on the main repo as example then is not properly working with the latest langfuse

I looked around and it seems to be this line info = assistant_message.get("info", {})

the assistant message has not attribut info. only a string on message

working on a fix right now, will raise a PR once done

@sao-coding can you check whether this issue is fixed with the latest version of the example?

[rossm-mf]

I can confirm on my side already that it's fixed

langfuse 2.71 with openwebui 0.3.29

[marcklingen]

awesome, glad that it works again. this was on me, broke this with my latest edit to the example. Now the token counts should be tracked correctly to support cost tracking in Langfuse for openwebui usage
