How to Add Error Handling to a Lindy Workflow (2026)

Last updated: 2026-07-06

One of my Lindy workflows broke last month.

Not in a dramatic way — it just stopped. The agent ran, hit a step where a file upload failed, and the whole sequence died. I came back to check on it and found nothing had happened.

My first instinct was to rebuild the workflow from scratch. Add a bunch of conditional logic. Make it more bulletproof from the start.

Instead, I started poking around. I remembered seeing the word “error” somewhere in the Lindy interface. I went looking for it.

What I found changed how I build every agent now.

The Hidden Right-Click Feature

If you right-click on any action inside a Lindy workflow, a menu appears. Most people know about the usual options — rename, duplicate, delete. But one option is easy to miss: add error handling.

What it does is simple but powerful. It lets you define what happens if that specific action fails. Instead of the whole workflow stopping dead, you create a branch — a route the agent takes when things go wrong.

You pick a step and say: if this fails, go here next. The agent follows that path, handles what it can, and keeps moving rather than stopping entirely.

I had no idea this existed. I discovered it by accident, almost out of frustration. The fact that most Lindy tutorials don’t cover it suggests a lot of people don’t know about it either.

Why Workflows Break (And It’s Not the Prompt)

If you’ve been building agents for a while, you’ve probably experienced the same thing: a workflow that looks perfectly designed still breaks in production.

The failure is usually not what you think.

Most people assume their prompt is wrong, or the trigger isn’t configured right, or the integration needs to be rebuilt. Those things can be issues, but the more common culprit is simpler: there’s no plan for when one step fails. And steps fail all the time.

Files don’t always upload. External APIs occasionally time out. A response comes back in an unexpected format. A Google Sheet row doesn’t exist where the agent expected it to be. Any of these can happen on any given run, and if the workflow has no contingency, it stops.

A client of mine was dealing with this on an agent that updated a Google Sheets spreadsheet. It kept failing because the agent couldn’t always locate the correct row before attempting to update it. The fix wasn’t a better prompt — it was adding a search step that ran first, confirmed the row existed, and gave the agent the context it needed to proceed. Making the agent search before it acts makes the whole thing more robust.

That’s exactly what error handling does at the action level.

How to Add Error Handling to a Lindy Workflow

The process is straightforward:

1. Open any Lindy workflow you’ve built
2. Find the action most likely to fail — usually an external integration like a file upload, an API call, or a step that depends on external data being in a specific format
3. Right-click on that action
4. Select “add error handling”
5. Choose a step to route to if that action fails

You can route to a notification step (send yourself a Slack or email alert so you know something went wrong), a fallback action, or just the next step in the sequence so the workflow continues without the failed output.

The key insight is that you don’t have to handle every possible failure from the start. Build the basic workflow first, run it, and add error handling to the specific steps that actually fail in practice. That’s more efficient than trying to anticipate every edge case before you’ve seen any of them.

A More Reliable Agent Without a Rebuild

After I added error handling to my broken workflow, it ran without issue the next day. The file upload failed again — same as before — but this time the agent routed around it, logged the failure, and continued processing everything else.

I would have spent an hour rebuilding that workflow from scratch. Instead, I spent five minutes adding one branch.

The broader lesson here is that the best workflows aren’t the ones that never fail. They’re the ones that keep running when something inevitably goes wrong. Error handling is how you build that resilience without overengineering everything upfront.

If you’re using Lindy and you haven’t explored error handling yet, spend five minutes on your most critical agent. Right-click the most fragile action. Add a branch.

Your future self will notice the difference.
