Rails 6.1 undefined method `[]' for nil:NilClass (NoMethodError)

[Ahmad]

When I try to run rails g migration clearance:install
I get:

	 1: from /Users/ahmgeek/.rvm/gems/ruby-2.7.2/gems/clearance-2.3.0/lib/generators/clearance/install/install_generator.rb:126:in `migration_primary_key_type_string'
