Creating a VPC returns nil

[joaomarceloods]

Creating a VPC returns nil. I believe it should return at least the id of the newly-created VPC, so you can find it.

Snippet to reproduce:

require "droplet_kit"
client = DropletKit::Client.new(access_token: "your_token")
vpc = DropletKit::VPC.new(name: "example", region: "nyc3")
client.vpcs.create(vpc) # => nil

Using droplet_kit-3.8.0
