调研方向

Start by reproducing the workflow with a Direct Reply node inside a loop or iteration using the Docker deployment and the affected versions. Trace the loop execution and streaming behavior from that node; the issue is done when execution completes all iterations, streams the first result, and raises no error.

Steps to reproduce

Deploy the application using Docker with version 1.61.1 and/or 1.17.1.

Create a workflow that contains a loop/iteration.

Add a Direct Reply node inside the loop body and inside the iteration.

Execute the workflow and observe the behavior.

✔️ Expected Behavior

The Direct Reply node should work normally inside the loop body and inside the iteration.

Streaming output should be supported.

Execution should not throw an error or stop after only the first iteration.

The result of the first iteration should be streamed successfully.

❌ Actual Behavior

Adding a Direct Reply node inside the loop body and inside the iteration immediately causes an error, or execution stops after only the first iteration.

The result of the first iteration is not streamed.

This issue did not seem to occur before.
