External Runners

Questions
1

Describe the problem/error/question:

JavaScript code node executions are not being picked up by the external runners at all which ceases operation of workflows that depend upon the node.

What is the error message (if any)?

Task request timed out after 60 seconds

Your Code node task was not matched to a runner within the timeout period. This indicates that the task runner is currently down, or not ready, or at capacity, so it cannot service your task.

If you are repeatedly executing Code nodes with long-running tasks across your instance, please space them apart to give the runner time to catch up. If this does not describe your use case, please open a GitHub issue or reach out to support.

If needed, you can increase the timeout using the N8N_RUNNERS_TASK_REQUEST_TIMEOUT environment variable.

Please share your workflow

The workflow contents are irrelevant: I cannot get a simple workflow with an unmodified code node to execute the code node

Information on your n8n setup

  • n8n version: 2.3.2
  • Database (default: SQLite): PostgreSQL
  • Running n8n via (Docker, npm, n8n cloud, desktop app): Podman Quadlets (essentially Docker for these purposes)
  • Operating system: Fedora 43 Server

I can provide detailed logs as well, upon request, but have been banging my head against a wall trying to solve this for the last day and a half.

What am I missing? I really hope this is resolvable as it is not negotiable the use of the code nodes and didn’t expect the update to go so rough.

Hi @Buggy_Arbor,

I am assuming you’re running in queue mode. If so, then you must point your runner to the worker’s broker. See below post where I have an example docker compose. My runner points to the worker and not the main instance.
