Wallaby does not set Selenium sessionId correctly.

Driver

Correct Configuration

• I confirm that I have Wallaby configured correctly.

Current behavior

{:ok, session} = Wallaby.start_session(capabilities: %{browserName: "chrome"})


%Wallaby.Session{
capabilities: %{browserName: "chrome"},
driver: Wallaby.Selenium,
id: nil,
screenshots: [],
server: :none,
session_url: "http://localhost:4444/wd/hub/session/",
url: "http://localhost:4444/wd/hub/session/"
}

Expected behavior

%Wallaby.Session{
capabilities: %{browserName: "chrome"},
driver: Wallaby.Selenium,
id: 1a2960426d5a3a6c369a1eec379ae06c,
screenshots: [],
server: :none,
session_url: "http://localhost:4444/wd/hub/session/1a2960426d5a3a6c369a1eec379ae06c",
url: "http://localhost:4444/wd/hub/session/1a2960426d5a3a6c369a1eec379ae06c"
}

Test Code & HTML

TL;DR;

diff lib/wallaby/selenium.ex:109
-  id = response["sessionId"]
+ id = response["value"]["sessionId"]

The response map is blow. Note that "sessionId" is a child of "value", not a sibling.
%{"value" => %{"capabilities" => %{"acceptInsecureCerts" => false, "browserName" => "chrome", "browserVersion" => "104.0.5112.79", "chrome" => %{"chromedriverVersion" => "104.0.5112.79 (3cf3e8c8a07d104b9e1260c910efb8f383285dc5-refs/branch-heads/5112@{#1307})", "userDataDir" => "/tmp/.com.google.Chrome.jtS7T2"}, "goog:chromeOptions" => %{"debuggerAddress" => "localhost:41055"}, "networkConnectionEnabled" => false, "pageLoadStrategy" => "normal", "platformName" => "LINUX", "proxy" => %{}, "se:cdp" => "ws://172.19.0.3:4444/session/5d5bb508ca9af813883d1a1908ac60f4/se/cdp", "se:cdpVersion" => "104.0.5112.79", "se:forwardCdp" => "ws://172.19.0.4:4444/session/5d5bb508ca9af813883d1a1908ac60f4/se/fwd", "se:vnc" => "ws://172.19.0.3:4444/session/5d5bb508ca9af813883d1a1908ac60f4/se/vnc", "se:vncEnabled" => true, "se:vncLocalAddress" => "ws://172.19.0.4:7900", "setWindowRect" => true, "strictFileInteractability" => false, "timeouts" => %{"implicit" => 0, "pageLoad" => 300000, "script" => 30000}, "unhandledPromptBehavior" => "dismiss and notify", "webauthn:extension:credBlob" => true, "webauthn:extension:largeBlob" => true, "webauthn:virtualAuthenticators" => true}, "sessionId" => "5d5bb508ca9af813883d1a1908ac60f4"}}

The hack above works but.. I do not know how the other drivers work or how this code should look. You might want to remove the "value" key in httpclient.ex and return just the value of "value".

To reproduce, fire up docker

docker run -d -p 4442-4444:4442-4444 --net grid --name selenium-hub selenium/hub
docker run -d --net grid -e SE_EVENT_BUS_HOST=selenium-hub \
-e SE_EVENT_BUS_PUBLISH_PORT=4442 \
-e SE_EVENT_BUS_SUBSCRIBE_PORT=4443 \
-v ${PWD}/config.toml:/opt/bin/config.toml \
-v /tmp/assets:/opt/selenium/assets \
-v /var/run/docker.sock:/var/run/docker.sock \
selenium/node-docker

Then run
{:ok, session} = Wallaby.start_session(capabilities: %{browserName: "chrome"})

Note your nil sessionId

And for anyone looking to setup Selenium with dynamic guests, you will need to hack hackney's timeout option in wallaby

config :wallaby,
  driver: Wallaby.Selenium,
  hackney_options: [timeout: 120_000, recv_timeout: 120_000,  pool: :wallaby_pool]
