I can't generate Test Data.

Hey @nandhu-nr! I'm here to help you with that issue. Let's get to the bottom of it together.

The ExceptionInRunner error occurs when an exception is raised in the executor, specifically when the results from the executor are empty, indicating that the runner thread encountered an issue. To debug this, you should review the traceback provided in the error message. Additionally, since you have set raise_exceptions=False, it should only show a warning message instead of raising the exception, but it seems like the exception is still being raised.

You might want to check if there are any issues with the input documents or the configuration of the generate_with_langchain_docs function. Ensure that the documents parameter is correctly formatted and that all other parameters are set as expected. If the problem persists, consider checking for any updates or patches to the Ragas library that might address this issue.

For similar issues, you can refer to the closed issue Testset generation. ValueError: a cannot be empty unless no samples are taken, which was resolved by a pull request ^[1].
