Steps to Reproduce

Stripe.Subscription.update(subscription_id, %{
  items: [
    %{
      id: params.item_id,
      price: params.item_price
    }
  ],
})

mix dialyzer

Expected Result

Dialyzer is happy as passing item ids to subscription update method is valid.

Actual Result

The function call will not succeed.

Stripe.Subscription.update(_subscription_id :: nil | binary(), %{:items => [%{:id => binary(), :price => _}, ...]}) ::
[...]

will never return since the 2nd arguments differ
from the success typing arguments:

[...]
 :items => [
    %{
      :billing_thresholds => binary() | map(),
      :metadata => map(),
      :plan => binary(),
      :price => binary(),
      :price_data => map(),
      :quantity => integer(),
      :tax_rates => binary() | [any()]
    }
  ],
[...]
