Adding a new Card in Stripe using Rails always says Missing required param: source

Question

I'm really stuck as to why I can't get this error to leave me be!

I'm trying to add a new card to an existing user through the Stripe API, the Stripe Gem and stripe.js

Server Log: (i've truncated values since the hashes are quite long):

Started PATCH "/users/11/billing" for xxx.xxx.xxx.xxx at 2016-01-09 05:47:50     +0000
Processing by UsersController#update_billing as HTML
Parameters: {"utf8"=>"✓",   "authenticity_token"=>"kKgMt...ItQ==", "user"=>  {"stripe_card_token"=>"tok_17RFZpHrpi1EikTto5nCO0", "plan_id"=>""}, "id"=>"11"}
Stripe error while updating card info: Missing required param: source.

User.rb method:

def update_card(subscriber, stripe_card_token)
  # customer is created correctly
  customer = Stripe::Customer.retrieve(subscriber.stripeid)
  puts customer
  customer.sources.create(:source => stripe_card_token)
  customer.save
  rescue Stripe::InvalidRequestError => e
    logger.error "Stripe error while updating card info: #{e.message}"
    errors.add :base, "#{e.message}"
    false
end

returned customer (from the puts customer)

Some notes that I've checked:

I get the same error before and after I've updated the STRIPE API I'm on the most recent Stripe API version (2015-10-16) The stripe gem is version 1.3.1 (October 29, 2015) Rails 4.2.2

This error message means that in your code:

customer.sources.create(:source => stripe_card_token)

stripe_card_token is nil.

Remember that you can view all requests sent with your API key in your dashboard. For example, to view all failed non-GET requests sent with your test API key: https://dashboard.stripe.com/test/logs?success=false&method=not_get
