Hi Instructor 

In Grid 4 I ran HUB

java -jar selenium-server-4.0.0-alpha-6.jar hub
16:25:21.660 INFO [LoggingOptions.getTracer] - Using OpenTelemetry for tracing
16:25:21.661 INFO [LoggingOptions.createTracer] - Using OpenTelemetry for tracing

16:25:22.348 INFO [Hub.execute] - Started Selenium hub 4.0.0-alpha-6 (revision 5f43a29cfc): http://10.0.0.190:4444

Then I tried to Run HUB:

macbookpro16@Monals-MacBook-Pro Module29_Selenium_Grid_4 % java -jar selenium-server-4.0.0-alpha-6.jar node --detect-drivers --publish-events tcp://2601:644:4480:e2c0:0:0:0:8f1f%en0:4442 --subcribe-events tcp://2601:644:4480:e2c0:0:0:0:8f1f%en0:4443
"--detect-drivers": couldn't convert "--publish-events" to a boolean

But it did not worked therefore; I tried like so

macbookpro16@Monals-MacBook-Pro Module29_Selenium_Grid_4 % java -jar selenium-server-4.0.0-alpha-6.jar node --detect-drivers --publish-events tcp://[2601:644:4480:e2c0:0:0:0:8f1f%en0]:4442 --subcribe-events tcp://[2601:644:4480:e2c0:0:0:0:8f1f%en0]:4443
zsh: no matches found: tcp://[2601:644:4480:e2c0:0:0:0:8f1f%en0]:4442

But that also did not worked so I tried with removing the [ ] in tcp:..

macbookpro16@Monals-MacBook-Pro Module29_Selenium_Grid_4 % java -jar selenium-server-4.0.0-alpha-6.jar node --detect-drivers --publish-events tcp://2601:644:4480:e2c0:0:0:0:8f1f%en0:4442 --subcribe-events tcp://2601:644:4480:e2c0:0:0:0:8f1f%en0:4443
"--detect-drivers": couldn't convert "--publish-events" to a boolean

Even that did not worked, so I tried removing --detect-drivers as you recommended in your lecture window

macbookpro16@Monals-MacBook-Pro Module29_Selenium_Grid_4 % java -jar selenium-server-4.0.0-alpha-6.jar node --publish-events tcp://2601:644:4480:e2c0:0:0:0:8f1f%en0:4442 --subcribe-events tcp://2601:644:4480:e2c0:0:0:0:8f1f%en0:4443
Was passed main parameter '--subcribe-events' but no main parameter was defined in your arg class
Usage: node [options]
Options:
--allow-cors ...

So I just tried with 

macbookpro16@Monals-MacBook-Pro Module29_Selenium_Grid_4 % java -jar selenium-server-4.0.0-alpha-6.jar node
16:44:36.596 INFO [LoggingOptions.getTracer] - Using OpenTelemetry for tracing

and then I tried to execute the Java Code by chainging the URL to http://10.0.0.190:4444 in my Java Code

String gridAddress = "http://10.0.0.190:4444";

later Ran the Code and it opened the Chrome Browser and went to

https://www.qtpselenium.com/ 

Looking at the Terminal see below:

Starting ChromeDriver 85.0.4183.87 (cd6713ebf92fa1cacc0f1a598df280093af0c5d7-refs/branch-heads/4183@{#1689}) on port 14514

ChromeDriver was started successfully.
16:46:19.445 INFO [ProtocolHandshake.createSession] - Detected dialect: W3C

Question: So I need to know did I do correctly ? Do I need to enter those tcp address ? 

Als My tcp addres looks like this tcp://[2601:644:4480:e2c0:0:0:0:8f1f%en0]:4442 --subcribe-events tcp://[2601:644:4480:e2c0:0:0:0:8f1f%en0]:4443

So here do I need to remove brackets [] ? or does not matter

Can you please let me know other ways I sould try to make the code run like you showed in the lecture videos ?

Thank you,

Monal
