I am not able to get the exception that was thrown when a Cucumber test failed in Java using the above method logError

Sorry about that, but I worked on this code over four years ago and wouldn't be able to assist you try to find why it's not working for you. Maybe AI such as Chat GPT or stack overflow may be a good place to get help on it, or perhaps TestRail's api documentation.
