Deploying with Heroku

Solving issue with Sqlite3

If using Sqlite3 you have the next error with Heroku Detected sqlite3 gem which is not supported on Heroku: To solve it follow the article here or DHH video (look about 29min45s)
Run rails db:system:change --to=postgresql then bundle

Solving issue with Gemfile.lock

I had issues with the Gemfile.lock and with the next error

Your bundle only supports platforms ["x86_64-darwin-19"] but your local
platform is x86_64-linux. Add the current platform to the lockfile with
`bundle lock --add-platform x86_64-linux` and try again.

It's been solved by removing my Gemfile, bundling and running bundle lock --add-platform x86_64-linux
A good article about it here
