Using Capybara how to disable "wait_for_pending_requests" as it raise an error - capybara

Question

I'm using Capybara with WebMock and a proxy (Sinatra) to test a remote app.
I'm not stubbing the requests but using WebMock to assert requests. I've assigned the proxy to capybara.app and added to the chrome driver so the requests will be forwarded to the proxy.
My problem is that sometimes I have pending requests which will raise the following error:
Failure/Error: raise "Requests did not finish in 60 seconds"
I wonder how can I disable this error?
Also how can I change the hard coded timeout which is 60 (which will block the continuation of the test anyway)
Timeout.timeout(60) { sleep(0.01) while #middleware.pending_requests? }
capybara.rb:
require 'capybara/rspec'
require 'capybara'
require 'capybara/dsl'
require_relative 'sinatra_proxy'
require 'selenium/webdriver'
require 'selenium/webdriver/remote/http/curb' if !isWindows
Capybara.server_port = 9980
Capybara.register_driver :selenium_chrome do |app|
http_client = isWindows ? nil : Selenium::WebDriver::Remote::Http::Curb.new
options = {
http_client: http_client,
browser: :chrome,
switches: [
"--proxy-server=0.0.0.0:9980",
"--disable-web-security",
'--user-agent="Chrome under Selenium for Capybara"',
"--start-maximized",
'--no-sandbox',
]
}
Capybara::Selenium::Driver.new app, options
end
Capybara.default_driver = :selenium_chrome
Capybara.app = SinatraProxy.new
Capybara.server_host = '0.0.0.0'
Capybara.default_max_wait_time = 8
Sinatra proxy:
require "sinatra"
require 'net/http'
require 'json'
file = File.read 'config.json'
config_json = JSON.parse(file)

HEADERS_NOT_TO_PROXY = %w(transfer-encoding)
class SinatraProxy < Sinatra::Base
# configure :development do
# register Sinatra::Reloader
# end
def request_headers

.collect {|pair| [pair[0].sub(/^HTTP_/, ''), pair[1]]}
.to_h # Ruby 2.1
.merge('CONTENT-TYPE' => request.env['CONTENT_TYPE'] || 'application/json')
end

# puts "REQUEST HEADERS #{request_headers}"

You can't change the timeout for waiting during reset, however you shouldn't be setting Capybara.app to your proxy app to start with. Capybara.app is meant for your AUT (application under test) where any requests that hang for more than 60 seconds after being told to quit is definitely an error. Since your proxy isn't your AUT just run it separately and tell Capybara not to run a server/app.
Capybara.run_server = false
Thread.new do
Rack::Handler::Puma.run(SinatraProxy.new, Host: '0.0.0.0', Port: 9980) # You might need/want other options here or to use thin/webrick/etc
