Code node task was not matched to a runner within the timeout period

[Uddeep]

Describe the problem/error/question

I run docker stack with n8n, n8n-worker, postgresdb and redis. It was all fine until i upgraded to 2.0.3. I have added n8n-runner as its needed for code node.
After upgrade of n8n to 2.0.3 with task runners implemented, i get “Code node task was not matched to a runner within the timeout period” for code node for both python and javascript.

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.

Since you are running in queue mode and offloading manual executions to workers, I think you need the broker URI to be http://n8n-worker:5679 as the n8n instance won’t be handling any workflow requests directly
