Dify version

1.5.1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

I update dify from version 1.2.0 to 1.5.1 and do some retrieval test on RAGFlow(version 0.19.1). Both Dify and RAGFlow are deployed via Docker and are installed on the same machine. To avoid conflicts and ensure smooth operation, I adjusted the conflicting port settings by specifying custom ports using the -p parameter in the Docker Compose command. The original version 1.2.0 functioned without issues.

✔️ Expected Behavior

There should be some results in retrieval test.

❌ Actual Behavior

Image There is no any results in the test. It doesn't work in chatflow, too. I check the result in RAGFlow. In RAGFlow, the retrieval test works. I roll back the dify version to 1.2.0 and recall the test to obtain the results.

Hi, @Killian-Filippov. I'm Dosu, and I'm helping the Dify team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You reported that after updating Dify from v1.2.0 to v1.5.1 in a self-hosted Docker setup with RAGFlow, external knowledge base retrieval stopped working.
  • Despite adjusting ports, retrieval tests and chatflow fail in v1.5.1, while rolling back to v1.2.0 restores functionality.
  • No additional troubleshooting or updates have been provided since the initial report.

Next Steps:

  • Please let me know if this issue is still relevant with the latest version of Dify by commenting here to keep the discussion open.
  • Otherwise, this issue will be automatically closed in 15 days.

Thank you for your understanding and contribution!
