I haven’t been able to test OCaml solutions for problems recently. I’m not sure but it may have started after the update of the test runner to version 2. Running the test runner locally using docker seems to work, but no matter what exercise I try, when using the web interface to run the tests I get the error:
An error occurred while running your tests. This might mean that there was an issue in our infrastructure, or it might mean that you have something in your code that’s causing our systems to break.
I haven’t tried submitting a problem through the CLI but I think at least the web interface doesn’t seem to be working properly.
