Getting “ArgumentError (wrong number of arguments

Question

I am using the Rolify Gem on a Rails application. This has worked well until today. I was installing webpacker and stimulus and while doing that ran Bundle Update. This appears to have broken my Rolify functionality.

Examined User model carefully and compared to another app where Rolify is still working. Checked Role model, checked database schema to ensure users_roles table is intact.

Is there anything in a polymorphic relationship that could cause that Argument error?

I apologize if this question is not well formulated, this is my first time asking a question here.

u=User.find(1)

=> #<User id: 1, email: "[e-mail]", created_at: "2019-04-27 17:13:17", updated_at: "2019-06-08 16:24:03", roles_mask: nil, first_name: "admin", last_name: "administrator", authentication_token: "V9rJdmKrhvZxVzBH55wk", email_frequency: nil, last_emailed: nil> 

u.roles

Traceback (most recent call last):
ArgumentError (wrong number of arguments (given 3, expected 2))

I get the following error: ArgumentError (wrong number of arguments (given 3, expected 2))

What fixed it for me was that I had to upgrade my ransack gem to ~ 2.1 per:
