Well, that didn't go to plan...

API downtime
Incomplete payloads
Bad calculations go unnoticed

🛠 Your n8n error-catching toolbox

Stop and Error

The n8n Stop and Error node icon, a red warning triangle with an exclamation mark, used as a circuit breaker to halt workflow execution

Circuit breaker → controlled errors

Stop and Error

Stop and Error node configured with a custom error message: Registration rejected: missing user_id

Circuit breaker → controlled errors

Chained validation pattern: an If node checks if User ID exists, routing to a Stop and Error for missing user_id on failure, then a second If node checks if Email exists, routing to a Stop and Error for missing email on failure, with valid data continuing through the True branches

Let's practice!
