Hello,

Since this week, Langfuse has been updated to version 3.

When I was running the filter function from https://github.com/open-webui/pipelines/blob/main/examples/filters/langfuse_filter_pipeline.py in my open webui I've got error:

(500, "'Langfuse' object has no attribute 'trace'")

To solve the problem I suggest to fix the langfuse version in the script as instructed in the Langfuse doc: https://langfuse.com/docs/sdk/python/low-level-sdk
In the documentation:

%pip install "langfuse<3.0.0"

In the langfuse filter script:

"""

description: A filter pipeline that uses Langfuse.
requirements: langfuse<3.0.0

Confirmed that updating langfuse_filter_pipeline.py to 1.7.1 resolves the error.

I think this issue can be closed.
