You can always sleep better, if your flow is made bulletproof so it does not fire any errors 😃  
But there is Catch node of course

There is no such thing as initiating a flow. You can use a catch node to detect errors, then if appropriate you can send a message from the catch node to perform whatever action you want (such as retrying whatever has caused the error).
