Can't find mistake in my code

Hi! Maybe one of You will see my mistake, I can't. The task is: Implement a to_s method on the BankAccount class that displays the name and balance in the following format (without brackets): Name: [name], Balance: [balance] It is not necessary to use the sprintf method to implement the balance printing.

And my code is: def to_s puts "Name: #{name}, Balance: #{balance.to_s}" end

Spaces are in good positions, I even tried to use .chomp on strings. Nothing works.

bank_account.rb 
class BankAccount
  attr_reader :name

  def initialize(name)
    @name = name
    @transactions = []
    add_transaction("Beginning Balance", 0)
  end

  def balance
    balance = 0
    @transactions.each do |transaction|
      balance += transaction[:amount]
    end
    balance
  end

  def debit(description, amount)
    add_transaction(description, -amount)
  end

  def credit(description, amount)
    add_transaction(description, amount)
  end

  def add_transaction(description, amount)
    @transactions.push(description: description, amount: amount)
  end

  def to_s
    puts "Name: #{name}, Balance: #{balance.to_s}"
  end

end
