Selenium 4, Microsoft Edge(chromium) on Ubuntu - selenium

Question

I am currently trying to get my automated tests working on chromium edge on ubuntu.
My current setup is this:
The setup is the following:
The browser is in a docker container with Ubuntu running
The hub is on the official Selenium 4 docker container
The tests or on a separate docker container running .Net Core 2.2
The RemoteWebDriver registration is the following
.....
var edgeOptions = new EdgeOptions();
edgeOptions.UseChromium = true;
edgeOptions.AddUserProfilePreference("download.default_directory", DownloadFolderPath);
edgeOptions.AddArguments("--no-sandbox"); // Bypass OS security model
edgeOptions.AddArguments("--ignore-certificate-errors"); // ignore ssl errors
edgeOptions.AddArgument("--disable-dev-shm-usage"); // ignore shm usage
edgeOptions.AddArguments("--ignore-urlfetcher-cert-requests"); // ignore url cert request fetch
edgeOptions.AddArguments("--force-devtools-available=1"); // ignore url cert request fetch
edgeOptions.AddArguments($"--lang={_language}"); //set browser language from the system properties.
GetEdgeDriver(builder, edgeOptions);
.......
private void GetEdgeRemoteDriver(ContainerBuilder builder, EdgeOptions options)
{
builder
.Register(_ => new RemoteWebDriver(new Uri(RemoteEndPoint), options.ToCapabilities(), TimeSpan.FromMinutes(5)))
.As<IWebDriver>()
.InstancePerLifetimeScope()
.OnActivated(x => x.Instance.FileDetector = new LocalFileDetector());
}
And we get this on the Node:

EDIT 2:
After updating to Java 11, the error from EDIT 1 is gone but I am still seeing issues running the tests. The grid at /status tells me it's up but when I try running tests I get this:

Answer 1

Remove:
"webdriver.edge.driver": "msedgedriver",
from capabilities, and add:
-Dwebdriver.edge.driver=/path/to/msedgedriver
to your node call. For example:
java -jar /path/to/selenium-standalone.jar -Dwebdriver.edge.driver=/path/to/msedgedriver -role node -nodeConfig /path/to/node-config.json
Ah, and your browserName must be MicrosoftEdge (you have it, but mentioning it for others reading this).
This worked for me for Selenium 3.
