Quick thought for the n8n community:
A workflow is not production-ready just because the happy path works.
If there is no logging, alerting, retry logic, error handling, or clear way to trace what happened when something fails, then it is still closer to a prototype than a dependable business process.
The real test is not, “Did it run once?”
The real test is, “What happens when the API times out, the data is incomplete, the AI response is messy, the rate limit hits, or the client needs to know exactly where things broke?”
That is where n8n builders can separate themselves.
Not just by building workflows that work when everything goes right, but by designing systems that still make sense when things go wrong.

I can’ agree more, in n8n moving from the prototype to production-ready but the real skill is in the “On error” settings and logging.

Really agree with this, especially the bit about the client needing to know exactly where things broke. The part I’d add is that almost everything in this thread lives inside the run, the on-error branch, the logging, the retry. That stuff is great but it only fires when n8n actually sees something go wrong. The failures that have burned me worst were the ones n8n never registered at all: a schedule that just didn’t fire one morning, an HTTP node that got a 200 back with an empty body so it sailed through as success, an expired token returning a polite empty payload. No error, no failed node, nothing for an error workflow to catch. The only way I’ve found to catch those is to check the actual outcome from outside the workflow, did the row land, did the file show up, rather than trusting that a green execution means the work happened. Logging tells you what ran. It doesn’t tell you what quietly didn’t.

Another angle that catches most teams off guard: idempotency. A workflow that runs correctly once can still create duplicate records or double-send messages when retried after a partial failure. Tracking processed state - a flag in your DB, or a processed_ids set in static workflow data - before any write or send operation is what separates a prototype from something safe to retry automatically.
