Hi @bastbu , after review, this should be considered a feature request. We will consider enabling logging in the tool in the future. Thank you for your feedback.

Is there any temporary solution in place? We are planning to use prompt flow in production and would like to add our own logs. Even setting my own logging configuration like this: logging.basicConfig(filename="sample.log", level=logging.WARNING") is not even saving my logs to any file.

Is there any solution to this? I can't see print statements either

Following up, even setting the below, I don't see any of my own logging output in the logs:

import logging
os.environ["PF_LOGGING_LEVEL"] = "DEBUG"
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)
