Questions
1

I started seeing duplicate executions for a single webhook call. Thought it was an n8n bug at first, has anyone experienced this

Describe the problem/error/question

What is the error message (if any)?

Please share your workflow

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

Information on your n8n setup

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Yeah, I have experienced this before

Upon research, I discovered that the sender retrying requests were because of any of the following reasons

  • my workflow response was slow and the proxy timed out so the same request was sent multiple times.

it can be fixed by any of this

by responding immediately using “Respond to Webhook” or adding idempotency checks and also by Logging request IDs to detect duplicates

you can try any of them, let me know which one works for you
