Steps to reproduce

Prepare an chatflow with 4 simple elements:

  1. user input
  2. LLM
  3. human input
  4. answer

Configure chatflow:

  • Human input prepare 2 options, and both connect with answer.
  • Change the chat settings to allow attachments.

(see the screenshot below in actual behavior)

Write a prompt, wait for answer and click any button from the Human input.

✔️ Expected Behavior

Click on the button is saved and chatflow is continued.

❌ Actual Behavior

Chatflow is stuck. Input prompt is disabled in the UI. Next click to any button shows an information in the upper right corner: This form has already been submitted by another user, form_id=...
