Langfuse_v3_pipeline not displaying trace data correctly

[darebfh]

I recently upgraded our openwebui/pipelines/langfuse setup and deployed gpt-oss. With the Langfuse_v3 pipeline, the traces show up in langfuse, however it seems as if the metadata cannot be structured:

To clarify: When opening the trace, I can see all details, however in the table above, the information does not show up (i.e., traces are not aggregated on per-user basis.

Openwebui version: v0.6.25
Langfuse version: v3.99.0 OSS
Pipeline (Langfuse_v3) version: 0.0.1 (https://github.com/open-webui/pipelines/blob/main/examples/filters/langfuse_v3_filter_pipeline.py)

I'm having this issue as well, wondering if a data structure changed with the lastest version of owui.

Here's what it used to look like for reference: https://cloud.langfuse.com/project/cloramnkj0002jz088vzn1ja4/traces/87275f28b45a8c0b5414ff0d9fd67d9a?timestamp=2025-08-22T11%3A15%3A19.006Z&display=details

I think something has changed, because the Opik filter stopped working properly too.

But anyway, fix is here: #557
