how can i achieve try and catch blocks in flows if any error i want to call the flow again? is this possible?
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).
