I'm having issues with the `api/public/

UPDATE: Issue resolved. Didn't run the DB migrations. I'm having issues with the api/public/dataset-run-items endpoint not returning trace_ids. DataRunItem requires a trace_id, but they don't appear in the response. Stacktrace in thread. Any ideas on how to fix this?

I have the latest for both my python langfuse library and the langfuse docker image

Looking at this right now for issues like this it’s best to directly post to GitHub with these debugging details I tried but could not reproduce this with the latest Python sdk and container version. Can you try again and post to GitHub if this issue persists? Sorry for the inconvenience! Currently making lots of improvements without meaning to break anything on the way (added lots of test to ensure backwards compatibility) @byron mackay

Hi Marc, I was able to get it fixed. I needed to update the DB. Sorry for the confusion.
