Getting Canopy to work with Selenium Hub locally

This is not an issue with how Canopy needing to be fixed. It is an issue with me not knowing what I am doing and also not knowing where to post questions about canopy other than here. I apologize for the length, I just want to get more info out there

I upgraded to version 1.5.1 of canopy (the minimum version to get chrome headless to work). For some reason I get errors when upgrading to 1.6 and I don’t know enough about F# to debug it.

I have a unit test in F# canopy that works great when I have “start chrome” as well as when I have “start ChromeHeadless”, but when I use this code to have it work in selenium hub:

let capability = new DesiredCapabilities()
capability.SetCapability("browser", "chrome")
        
// Setup Remote WebDriver to run on Selenium Hub
let remote = Remote("http://localhost:4444/wd/hub/", capability)

start remote

it kicks off this in my selenium hub command prompt:

12:15:09.159 INFO [RequestHandler.process] - Got a request to create a new session: Capabilities {browser: chrome}

12:15:09.170 INFO [TestSlot.getNewSession] - Trying to create a new session on test slot {server:CONFIG_UUID=97a96575-c281-41e8-a330-acf076e12e95, seleniumProtocol=WebDriver, browserName=chrome, maxInstances=5, platformName=WIN10, platform=WIN10}

and then nothing happens that I can see in the grid.

In case I did something wrong when setting up the grid the two commands I used were:

java -jar selenium-server-standalone.jar -role hub

in one browser and this in another

java -jar selenium-server-standalone.jar -role node -hub http://localhost:4444/grid/register

I can go to the grid console and see the browser icons like I am supposed to, so I assume its set up right.

I get the following error with my unit test in Visual Studio.

Message: Class Initialization method TestName.DetailTests+UnitTest.Setup threw exception. System.InvalidOperationException: System.InvalidOperationException: Unable to create session from org.openqa.selenium.remote.NewSessionPayload@11d55a1 Build info: version: ‘3.11.0’, revision: ‘e59cfb3’, time: ‘2018-03-11T20:33:15.31Z’

You need to specify browserName instead of browser let capability = new OpenQA.Selenium.Remote.DesiredCapabilities() capability.SetCapability(“browserName”, “firefox”) I also had this issue, but when modified to browserName it started to work.
