dify - 💡(How to fix) Fix retriever_resources empty in API response when Chatflow calls a child Workflow as tool (v1.12.1) [1 comments, 2 participants]

TL;DR

The issue with the empty retriever_resources array in the API response from the Chatflow execution may be due to a discrepancy between the interactive UI testing and the API response handling.

Guidance

• Verify that the Knowledge Retrieval node in the child Workflow is correctly configured and functioning as expected.
• Check the API endpoint and response handling code to ensure that it is properly parsing and including the retriever_resources array in the response.
• Compare the interactive UI testing and API response handling code to identify any differences in how the metadata is being processed and returned.
• Review the Dify version documentation (v1.12.1) to see if there are any known issues or limitations related to the retriever_resources array.

Example

No specific code example can be provided without more information about the API endpoint and response handling code.

Notes

The issue may be specific to the Self Hosted (Docker) environment, and it is unclear if this issue occurs in Cloud hosted environments.

Recommendation

Apply workaround: Modify the API response handling code to correctly parse and include the retriever_resources array in the response, if possible. This may involve debugging the code and identifying where the metadata is being lost or not properly processed.
