Cannot run script with run configurations

I have an application served by puma. Then I have some test script that makes calls to the server and verifies the results.

I run the test script with the ruby interpreter from the command line. It works. It uses test/unit gem to implement the tests.

I then tried to create a run configuration of the type ‘Ruby’,, that runs that script. When I execute the configuration I get the following output :

Could not find the cause. It worked without me installing anything, but then I installed the gem ‘test-unit’. same result.

I then turned to creating a remote debug configuration. There is a guide for that that I followed. I got up to the point where I have Open SSH running, the connection test is successful, and when I set the remote interpreter (which is on the same host), I click ‘OK’ but nothing happens. I have to click ‘Cancel’. Screenshot below :

I then even tried a run configuration of the type ‘Ruby Console’, with the console type IRB. I got the same error than the one in the stack trace above.

Any help appreciated
