Password Expirable no implicit conversion of Symbol into String error.

Hello there,

I started using the password_expirable feature of the gem. The form renders correctly, but when I fill it,
the application pops this error:

Has anyone run into the same issue? Is there a known solution for it?

Thanks in advance.
