Chat UI in Agentic Flow shows delayed responses, duplicated/infinite executions, and incomplete chat clearing

[Abhishek514964]

Describe the bug

In Flowise Agentic Flow chat UI, messages do not reliably render or behave correctly. The chat often does not respond immediately after sending a message; the response only appears after closing and reopening the chat. On reopening, the UI shows multiple executions for what was a single user message. Clearing the chat does not fully clear all messages—some previously shown messages remain visible. Additionally, sending a single message (e.g., “hello”) can trigger infinite repeated executions for the same message, visible in the Executions window.

To Reproduce

1. Open Flowise and navigate to an Agentic Flow.
2. Open the chat UI for the Agentic Flow.
3. Create a valid flow.
4. Send a simple message (e.g., “hello”).
5. Observe that the chat often does not respond immediately.
6. Close the chat UI and reopen it.
7. Observe that the response appears only after reopening, and the same single message may show multiple executions.
8. Click “Clear messages” / clear chat in the UI.
9. Observe that some chat messages are still displayed and the UI does not fully reset.
10. Check the Executions window while/after sending a single message.
11. Observe repeated/infinite executions for the same message.

Expected behavior

• The chat should respond immediately after a message is sent, without requiring the chat to be closed and reopened.
• Each user message should create exactly one execution (unless explicitly designed otherwise).
• Reopening the chat should not duplicate executions or replay the same message multiple times.
• Clearing messages should remove the entire chat history from the UI consistently.
• Sending one message should not trigger infinite/repeated executions.

Screenshots

No response

Flow

Not flow-specific. Reproducible across all Agentic Flows (any exported flow shows the same behavior).

Additional context

• Issue occurs specifically with Agentic Flow chat UI.
• Duplications and infinite executions are visible in the Executions window even when only one user message is sent.
• Clearing chat does not reliably clear the full UI history (some messages persist).
