Sqlite and BigDecimal errors

[jgomo3]

I had to change sqlite3 to gem 'sqlite3', '~> 1.3.13' in the Gemfile. If not, I received the following error:

App 31334 output: Error: The application encountered the following error: Specified 'sqlite3' for database adapter, but the gem is not loaded. Add gem 'sqlite3' to your Gemfile (and ensure its version is at the minimum required by ActiveRecord). (Gem::LoadError)

Also, with Ruby 2.7 I received the following error, so I'm using Ruby 2.3.8.
