API and Playground error - "Run failed. Sorry, something went wrong"


  • Go to Playground, create new Assistant
  • Switch on “Retrival” and add PDFs.
  • Ensure Streaming response is On.
  • Run a prompt that uses the docs/PDFs.
  • Runs are streamed and you start getting response. But suddenly it is cut half way with “Run failed”.

I was getting this via API but I could isolate the problem once I tried using Playground and I can reproduce this issue.

You use Streaming Response with Retrieval., and I repeatedly getting error where response are cut/stopped half way…
“Run failed. Sorry, something went wrong.”

It would be generating content, and just fail!

Turns out, this issue occurs when prompt asks for Citations or response includes Citations. If I explicitly ask not to include Citations, error goes away via API or via Playground!
