Invalid JSON body in LoadBalancer create requests using defaults

[andrewsomething]

As originally reported in a comment to #140, attempting to create a load balancer without explicitly setting the boolean values for enable_proxy_protocol and redirect_http_to_https will result in an invalid JSON body. Both attributes are set to null by default resulting in a 500 response from the API.

Script to reproduce:

#!/usr/bin/env ruby
require 'droplet_kit'
require 'json'

token = ENV['DO_TOKEN']
client = DropletKit::Client.new(access_token: token)

load_balancer = DropletKit::LoadBalancer.new(
  name: 'example-lb-03',
  # enable_proxy_protocol: false,
  # redirect_http_to_https: false,
  algorithm: 'round_robin',
  tag: 'web',
  region: 'nyc3',
  forwarding_rules: [
    DropletKit::ForwardingRule.new(
      entry_protocol: 'http',
      entry_port: 80,
      target_protocol: 'http',
      target_port: 80,
      certificate_id: '',
      tls_passthrough: false
    ),
    DropletKit::ForwardingRule.new(
      entry_protocol: 'https',
      entry_port: 444,
      target_protocol: 'https',
      target_port: 443,
      certificate_id: '',
      tls_passthrough: true
    )
  ],
  sticky_sessions: DropletKit::StickySession.new(
    type: 'cookies',
    cookie_name: 'DO-LB',
    cookie_ttl_seconds: 5
  ),
  health_check: DropletKit::HealthCheck.new(
    protocol: 'http',
    port: 80,
    path: '/',
    check_interval_seconds: 10,
    response_timeout_seconds: 5,
    healthy_threshold: 5,
    unhealthy_threshold: 3
  )
)


puts load_balancer.to_json

client.load_balancers.create(load_balancer)

Hi @andrewsomething - just following on from your message in #140, adding enable_proxy_protocol: false fixes my issue!

Great! Thanks for following up @jonnyarnold
