Why am I getting the “can't modify frozen String” error when I am not modifying the hash?

Question

I am getting the can't modify frozen String error on the User.create(name:name,email:email) . But I am not modifying the hash at all. All I am doing is creating a new User object with the hash name and email . I am not modifying them. Can someone please clarify as to why I am getting this? Thank you!

Code:

users = {'John' => 'john@john.com', 'Sara' => 'sara@sara.com'}
def create_users_from_hash(users)
  users.each do |name, email|
    User.create(name:name,email:email)
  end
end

You can use create! to find where is wrong.Sometimes error will be raised when you want to access an inaccessiable field.
