Stripe Webhook firing but Stripe event method not running - ruby-on-rails

Question

Using the stripe events gem I am trying to update a Stripe subscription on the event unsubscribe. My events are not firing even though they are receiving the webhook.
I am running my endpoint on ngrok and using the stripe-events gem. I have installed the stripe cli so I can see that the webhook events are firing.
My thinking is that there is a problem with the code I am trying to use
#user = User.find_by_stripe_id(event.data.object.customer) however I got this code from a thread on GoRails. Chris Oliver said that it looked correct and I have repurposed it for my app so that makes me think it might be something else.
# config/initializers/stripe_events.rb
Stripe.api_key = Rails.application.credentials.stripe_publishable_key
Stripe.api_key = Rails.application.credentials.stripe_signing_secret
StripeEvent.configure do |events|
events.subscribe "customer.subscription.updated" do |event|
#user = User.find_by_stripe_id(event.data.object.customer)
logger.info "Processing the request..."
if DateTime.now >= #user.subscription_end_date
logger.info "if statement is running..."
#user.update_attribute(subscribed: false)
#user.save!
end
end
end
I am not sure if this is needed but here is the method that triggers the webhook. I have added the DateTime.now-1 for testing if the webhook so that it simulates an expired subscription.
# app/controllers/subscriptions_controller.rb
def destroy
if Rails.env.production?
Stripe.api_key = Rails.application.credentials.stripe_live_api
else
Stripe.api_key = Rails.application.credentials.stripe_api_key
end
customer = Stripe::Customer.retrieve(current_user.stripe_id)
customer.subscriptions.retrieve(current_user.stripe_subscription_id)
Stripe::Subscription.update(current_user.stripe_subscription_id,:cancel_at_period_end => true)
##current_user.update(subscription_end_date: Time.at(customer.subscriptions[:data].first[:current_period_end]))
current_user.update(subscription_end_date: DateTime.now-1)
redirect_to root_path, notice: "Your subscription has been cancelled"
end
I tested the response from the stripe webhook

I'm not sure code in config/initializers/stripe_events.rb can have access to app/controllers once your app is launched.
You should call a service :
config/initializers/stripe_events.rb
StripeEvent.configure do |events|
events.subscribe "customer.subscription.updated" do |event|
StripeUdpateSubscription.new
end
end
app/services/stripe_update_subscription.rb
class StripeUpdateSubscription
def call(event)
..// you code here
end
end
