Dify version

1.9.1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

I have updated a Dify deployment from 1.8.1 to 1.9.1
In the previous version an iteration node had as output the result of a code node that was returning an Array of Objects.

When the parallel iteration ended, the result was an array of objects with a merged result of all the arrays

✔️ Expected Behavior

The result should be an array of objects

Actual Behavior

the result is an array of array of objects
