Why these guides spend so long on what goes wrong

Because that is the part the documentation leaves out. Below is n8n refusing to test-run a published Slack workflow — a real limit, with a real message, that appears nowhere in the docs. We found it by trying it, and now it's in the Slack guide instead of costing you an afternoon.

The n8n editor showing a Slack Trigger connected to a Handle Event node, with a red error toast reading: Problem running workflow — Because of limitations in Slack Trigger, n8n can't listen for test executions at the same time as listening for production ones. Unpublish the workflow to execute.
n8n 2.33.7 refusing a test run on a published Slack Trigger workflow. The message is accurate and undocumented.
