Dify version

1.8.1

Cloud or Self Hosted

Cloud, Self Hosted (Docker)

Steps to reproduce

<img width="1765" height="832" alt="Image" src="https://github.com/user-attachments/assets/2d72fc21-6403-44cb-91cb-9fbd56a708a2" /> <img width="1763" height="883" alt="Image" src="https://github.com/user-attachments/assets/f1f72840-f964-4c7a-9155-5d94b9e22304" /> I didn't see any results on the frontend interface. Sometimes it runs successfully, but it also very often fails to execute. The results can be seen correctly in the backend, just not on the frontend.

✔️ Expected Behavior

Normally, there should be a return of streaming data.

❌ Actual Behavior

It has been stuck in a running state for a long time without any response.

extent analysis

TL;DR

Investigate the discrepancy between backend and frontend results to resolve the inconsistent execution issue.

Guidance

  • Verify the streaming data is correctly generated in the backend and investigate potential issues with data transmission to the frontend.
  • Check the frontend code for any errors or inconsistencies that might prevent the display of streaming data.
  • Review the Dify version 1.8.1 documentation and release notes for any known issues related to streaming data or frontend-backend communication.
  • Test the application in different environments (Cloud and Self Hosted) to see if the issue is specific to one setup.

Example

No code snippet can be provided without more specific details about the application code.

Notes

The issue seems to be related to the communication between the backend and frontend, but more information about the application architecture and code is needed to provide a more specific solution.

Recommendation

Apply workaround: Investigate and resolve the backend-frontend communication issue, as upgrading to a fixed version is not implied in the given information.
