How to get full error message?

[elcolie]

I have put LANGFLOW_LOG_LEVEL=DEBUG in the environment variable, but still no meaning full messages from the terminal and log files.

langflow: 1.9.1
Ubuntu 24.04
python 3.12

How to get full UI error messages?

Hey @elcolie

Please try setting LANGFLOW_DEV=true in your env file.

LANGFLOW_LOG_LEVEL=DEBUG
LANGFLOW_DEV=true

Maybe the log level can be ignored, as you can see in logger.py 181

def remove_exception_in_production(_logger: Any, _method_name: str, event_dict: dict[str, Any]) -> dict[str, Any]:
    """Remove exception details in production."""
    if DEV is False:
        event_dict.pop("exception", None)
        event_dict.pop("exc_info", None)
    return event_dict
