'Detecting rails configuration failed' on Heroku - ruby-on-rails

I've updated my application from Ruby 2.7.7 to Ruby 3.0.5 and from Rails 5.2.0 to Rails 6.0.1.
After updating various Gems and fixing a variety of things I have it running well on my test server but when I try to load the new version on Heroku I get 'Detecting rails configuration failed' and it won't run. I'm guessing there's something in the configuration files that needs to be updated but I need some guidance on where to look next.
Here's the last part of the Heroku build (where it appears to deploy it) followed by the tail from the logs.

How to I get to the ROR app. Like it looks like the live site.
https://pcms.herokuapp.com/login
The app was designed by a previous developer in 2013. I just received the files two weeks ago. Having to update everything to latest versions of everything. I've added the database into the pgAdmin4.
I need to be able to see the changes in the localhost before pushing to heroku platform.

H12 timeout error on Heroku

Can anyone shed some light on what's causing this timeout error on Heroku (at 2012-07-08T08:58:33+00:00)? The docs say that it's because of some long running process. I've set config.assets.initialize_on_precompile = false in config/application.rb.
Specific error:
2012-07-08T08:58:33+00:00 heroku[router]: Error H12 (Request timeout) -> GET codicology.co.uk/ dyno=web.1 queue= wait= service=30000ms status=503 bytes=0

Are you loading something from codicology.co.uk during the deployment of your app? e.g. loading a custom buildpack that is hosted there?
If I visit codicology.co.uk I get a certificate error. Perhaps whatever process or request you're running from Heroku is getting a certificate error also which prevents it from properly connecting, or perhaps it decides to drop the connection because of the error.
If you can give us a bit more information about what you're trying to do or what codicology.co.uk is used for (do you own it?) perhaps we can help more.
