Easyposy-ruby gem 3.10 - 'no implicit conversion of Symbol into Integer' error when creating address.

[ccasabona]

After installing v 3.1.0, requests to create an address return 'no implicit conversion of Symbol into Integer'. Taking the boilerplate code form the easypost docs,

address = EasyPost::Address.create(
  street1: "417 MONTGOMERY ST",
  street2: "FLOOR 5",
  city: "SAN FRANCISCO",
  state: "CA",
  zip: "94104",
  country: "US",
  company: "EasyPost",
  phone: "415-123-4567"
)

The request returns:

{:status=>"no implicit conversion of Symbol into Integer"}

Reverting to 3.0.1 works as expected.

Rails 6.0.3.2
Ruby 2.7.1
