(RuntimeError) Wallaby had an internal issue with HTTPoison

Issue

When I switch to using Chrome, I get this error:

     ** (RuntimeError) Wallaby had an internal issue with HTTPoison
     stacktrace:
       (wallaby) lib/wallaby/httpclient.ex:32: Wallaby.HTTPClient.make_request/4
       (wallaby) lib/wallaby/experimental/chrome.ex:64: Wallaby.Experimental.Chrome.start_session/1

       test/school_web/features/view_test.exs:1: SchoolWeb.UserListTest.__ex_unit__/2

Versions:
elixir: "~> 1.4",

Test Code & HTML

Here's my test:

defmodule SchoolWeb.UserListTest do
  use SchoolWeb.FeatureCase, async: true

  import Wallaby.Query, only: [css: 2]

  test "homepage is accessible", %{session: session} do
    session
    |> visit("/")
    |> assert_has(css(".header", count: 1, text: "Welcome"))
  end
end

Here's my FeatureCase:

defmodule SchoolWeb.FeatureCase do
  use ExUnit.CaseTemplate

  using do
    quote do
      use Wallaby.DSL

      alias School.Repo
      import Ecto
      import Ecto.Changeset
      import Ecto.Query

      import SchoolWeb.Router.Helpers
    end
  end

  setup tags do
    :ok = Ecto.Adapters.SQL.Sandbox.checkout(School.Repo)

    unless tags[:async] do
      Ecto.Adapters.SQL.Sandbox.mode(School.Repo, {:shared, self()})
    end

    metadata = Phoenix.Ecto.SQL.Sandbox.metadata_for(School.Repo, self())
    {:ok, session} = Wallaby.start_session(metadata: metadata)
    {:ok, session: session}
  end
end

Here's my HTML:

<h1 class="header center">Welcome to School!</h1>
Thanks for any help you can give!

Thanks for the report @stephaniewilkinson. Can you confirm what version of chrome and chromedriver you have installed?

[stephaniewilkinson]

My Chrome is Version 66.0.3359.117 (Official Build) (64-bit)
My ChromeDriver is 2.37.544337 (8c0344a12e552148c185f7d5117db1f28d6c9e85)
I had previously tried on Chrome 65 with the same result.

For phantomjs I didn't customize the version, just ran this:

npm install -g phantomjs-prebuilt

I should probably mention the tests run fine before I try to switch to chrome.

[keathley]

Thanks! All of that looks correct to me. We get those httppoison errors when there’s an issue communicating with chromedriver. Based on the stack trace it looks like it’s not able to create a new session which typically indicates an issue with wallabys ability to talk to chromedriver or chromedrivers ability to talk to chrome.

[stephaniewilkinson]

Thanks! any ideas what to try next?

[keathley]

What OS are you using? Are both chrome and chromedriver in your path? Other things to try might be trying out the latest elixir and otp version.

Got an similar error:

Not sure if it's the same issue though.

I'm running macOS 10.13.5, Chrome 67.0.3396.79, ChromeDriver 2.40.565386, Elixir 1.6.5 (compiled with OTP 20).

We need to add more backoff and jitter to our http client. We see these issues when chromedriver starts to get overwhelmed with requests.

@keathley any update here? Am running into the same issue:

I'm working on tracking down the root cause but so far no luck. Without a way to reliably re-produce this issue locally its very difficult to ensure we have a proper fix. If you have a test case that you can provide that would greatly assist the effort here.

[keathley]

I've opened a PR that may help to reduce some of the issues that folks are seeing. If you would like to test out that branch locally that would be very useful.

[keathley]

The PR is now on master so if you'd like to test with that it would be very appreciated.
