Validation is broken in Rails 7

[5minpause]

Since this commit rails/rails@70dc990
the code to add errors to the record doesn't work anymore.

Current code:

nobspw/lib/active_model/validations/password_validator.rb

Line 22 in 21144cb

record.errors[attribute] << get_message(reason)

How it should work with Rails 7:

pc.weak_password_reasons.each do |reason|
  record.errors.add(attribute, get_message(reason))
end
