I left the same comment here not sure if it would be seen on a closed issue. #41

Hi @ebidel
I have recently had the same or a similar issue running lh-bot, i was hoping you might be able to help me troubleshoot it.

This is the error:
(I have had the same error occur on 3 different PRs, and have not yet been able to get the bot to comment in the pr)
"Error from CI backend. invalid json response body at https://builder-dot-lighthouse-ci.appspot.com/ci reason: Unexpected token U in JSON at position 0"

This is the PR in staging: https://website-ssr-pr-14.herokuapp.com/

Sorry, I haven't worked on this project for some time. I'm sure the team is maintaining the endpoint anymore.
