Error writing to outputs.http

Hi all,   About every 20 seconds I am getting these errors in the live logs of my published app (picture):     Does anybody know what this is or how I can fix this?   Thanks

I would try 2 things first:

  1. Enable TRACE logging to see if you can get more information
  2. Restart the app to see if it fixes the error.

Without more information it’s hard to tell where this is all going wrong
