LocomotiveCMS and Heroku - deployment issues

LocomotiveCMS and Heroku - deployment issues - ruby-on-rails

I followed the instructions for deploying a locomotivecms app to Heroku:
http://doc.locomotivecms.com/installation/heroku
heroku open command brings up an error page in the browser. heroku logs reveal following:

What does it mean? Thanks.

Turned out to be incorrect app name in the locomotive.rb file. The app name did not match the app name on Heroku.

Rails Heroku Application Error on Heroku Open

I am trying to start my Heroku app (Rails 6 / Postgres) by using heroku open, but I am encountering an 'Application Error'.
Earlier I was having issues with rails credentials, but I deleted and regenerated them and am no longer seeing the same errors as before.
EDIT:
Again, I ran rm credentials.yml.enc and EDITOR='subl -w' rails credentials:edit (just running rails edit:credentials prompts you to use an editor) and I got the following:
DEPRECATION WARNING: Including LoggerSilence is deprecated and will be removed in Rails 6.1. Please use `ActiveSupport::LoggerSilence` instead (called from <main> at /Users/spencer_kier/life-school-landing/config/application.rb:7)
File encrypted and saved.
And then I added, committed and pushed to Github, then ran heroku open and got the following (note that when I run heroku local everything is fine):

How to get rails app to work in production [heroku deployment]

In short: My application works fine in development using Devise, however in production I'm getting the error shown below. Bare in mind that I am using KatanaCode's BlogIt engine but I have re-built the user model, and schema and it is only using Devise's model.
github: https://github.com/Apane/Blogit_blog
Please advice.

Make sure the plugin you are using is properly loaded and listed in your Gemfile.

Keep getting 'Error H10 (App crashed) -> GET' when trying to deploy to Heroku

So I've been trying to deploy a rails app to heroku and have been having some issues. I did a good amount of poking around through the logs and on SO but couldn't find anything to point me in the proper direction. Then again I just might be missing something obvious. Anyway any help would be greatly appreciated.
Command
git push -f heroku master

Maybe the gem that you use to manipulate uploads and files is not installed. And remember that you can't use this gem without uploading your files to another server.

Heroku deployment issue - can you help me find the error?

My app works perfectly locally but on deployment it crashes. My Heroku log is below, i've already fixed a few issues but am now struggling to find the culprit. I'm aware of the Devise warnings, however, I can't see these being the cause....
Can anyone spot the offending error?
