Yesterday I did a sitespeed.io release that is automatically picked up by our systems. That release included a new version of bidi-har (Mozillas implementation to get a HAR file using bidi-webdriver). The new release includes a way to get response content (HTML/CSS/JS) in the in HAR file. However it sees like somehow that broke our system because we got a lot of error logs. I will do a manual rollback and will add an issue for Mozilla.
