Steps to reproduce

I was trying to figure out why my question classifier was routing to the wrong (and same one everytime) node. When debugging only the Question Classifier step, it showed that it found the correct classification but the routing choice to the next node did not match the result. I am frequently having to disconnect and reconnect the proceeding nodes to fix the issue.

✔️ Expected Behavior

The Question Classifier routes to the next node appropriately.

❌ Actual Behavior

The Question Classifier returns a proper result but routes to the incorrect node.

To address the issue with the Question Classifier routing to the incorrect node despite recognizing the correct classification, consider the following steps:

1. Review Classification Conditions: Ensure the conditions for each classification are clear and do not overlap, which could lead to incorrect routing.

2. Verify Model Configuration: Check the inference model and model provider settings to ensure they are correctly configured for accurate classification and routing.

3. Check Input Variables: Confirm that the input variable is correctly captured and passed to the Question Classifier without alterations.

For detailed guidance, refer to the Question Classifier documentation and ensure your Docker environment is configured correctly as per the Docker environment documentation.

Additionally, recent updates to the Dify codebase, particularly in api/core/workflow/nodes/question_classifier/template_prompts.py, might impact routing behavior. Review these changes for potential insights into the issue.

If the problem persists, providing specific logs or error messages could offer further insights into the misrouting issue.
