So the field you’re setting in render specifically wants a docker command. tournament/test/ExpressionFixtures/base.ts at main · n8n-io/tournament · GitHub
So per our documentation of queue mode you would want this command instead:
docker run --name n8n-queue -p 5679:5678 docker.n8n.io/n8nio/n8n worker
You can also check out this community post, though it mainly helps with using Render, rather than setting up queue mode.
