I keep getting this error whenever I try to run an experiment on the online Playground. Any idea on what's wrong? Do I need to run the tool locally?

What inputs (settings and document) are you testing? This indicates a general error with the back-end, but doesn't tell us the specific problem. For example, the LLM API may have thrown an error or there might have been an invalid token in your doc. I can try to reproduce if you send along your inputs.

the playground seems to be working fine now with all the same inputs. Maybe there was a server issue yesterday? Once again, thanks for the great work on this repo!

I'm having the same issue. Do I need to input any API key to use the front end playground?

The auto-evaluator tool is basically unusable at the moment for me because of this. Cannot even run the demo.
