Updated from 0.50.1 to 0.60 and get html errors

I just upgraded and I get the errors in the attached screenshot. I searched for fingerprinted = _FINGERPRINTED.match(request.match_info[‘filename’]) and the only match was for someone who was trying to customize the theme. So, I commented out the theme in my configuration.

I’m running on Ubuntu in a venv and used pip3 to upgrade. The only configuration parts that failed the hass --script check_config were related to the recorder so I fixed those.

Any ideas?

I figured it out. I opened the front end in an incognito window and it worked, which made me realize it was a caching issue that must be causing the website to request the wrong resource name. Of course, I figured this out after uninstalling and re-installing all of the packages in the venv and clearing the pip cache along with reading all of the breaking changes…

hopefully this helps someone else.
