dify - 💡(How to fix) Fix Workflow node returns data format exception [1 participants]

TL;DR

The issue can be resolved by checking the data type and structure of the conversion_fistory variable in the workflow node and ensuring it is compatible with subsequent nodes.

Guidance

• Verify the data type of conversion_fistory in the workflow node to ensure it is not an array of objects, which may be causing the issue.
• Check the documentation of subsequent nodes to confirm they can handle the data type and structure of conversion_fistory.
• Inspect the workflow configuration to ensure that the conversion_fistory variable is being passed correctly to subsequent nodes.
• Consider adding a debugging node to inspect the value and structure of conversion_fistory before it is passed to subsequent nodes.

Notes

The provided images do not offer sufficient information to determine the root cause of the issue, and the problem may be specific to the workflow configuration or node implementations.

Recommendation

Apply workaround: Modify the workflow configuration to ensure compatibility between the conversion_fistory variable and subsequent nodes, as the root cause is likely related to data type or structure mismatch.
