Unable to run test in server based tests getting "6711: Invalid debugger target"

[basilke]

The tests are shown in test manager. But when I run them, i get an error saying "6711: Invalid debugger target: ##class(%UnitTest.Manager).RunTest("username .. the rest is clipped off.

Now to give some back ground, we have different namespaces. The default is "SYS". But I am trying to run a test in another environment say "BASI". I can see the that the test copies the tested file to "SYS" :/_vscode/BASI/UnitTestRoot/UnitTest/testedClass.cls

The error also says cannot find the class which i have used in not present in "SYS". This error is valid, I am actually trying to test something in "BASI" not "SYS". Not sure why it thinks that namespace or test that I am using on in default namespace.

Thanks
