To Reproduce Ask the bot a question that triggers the Bedrock knowledge base fallback feature.

Expected behavior The bot should display the results retrieved from the Bedrock knowledge base.

Please complete the following information about the solution:

Screenshots Sample screenshot of empty response image Logs of empty response: image Connect flow I used: image

Additional context Based on testing and log analysis, the response is blank if the Bedrock knowledge base processing time exceeds 6-7 seconds.

Hi @dangollayan, thank you for reporting this. To help further investigate it -

  1. You mentioned you see response blank in connect. Could you please try comparing in QnABot's chat client? Does it show blank as well?
  2. Also, in your logs, could you also please provide an expansive screenshot of last line that says "INFO final:". It's the final response that is sent to clients that we need to look at.
  3. Have you checked logs from connect chat side to see if there any errors? You can also try to see browser console logs in chrome developer tools and network logs.

Hi @dangollayan, checking-in again if you have any further updates on the information I requested.

  1. Thanks
  2. I'll need expanded view of "final" (click dropdown on that line please) so I can look at the response.
  3. Also, on the frontend chat client side, I need to see browser console logs in chrome developer tools and network logs.
