HTTP Request exception handilng problem

[mich3000]

I just started learning node-red and i am trying to handle exception of HTTP request node.
When ECONNREFUSED error occurs i try to catch it with CATCH Node.
Error is catched with CATCH but also next node after HTTP Request is executed.
What i am doing wrong? Is this normal behavior?
Thanks

Hi,

Error is catched with CATCH but also next node after HTTP Request is executed

What about using a Switch node after your Http request to handle the direction you want your application to take in case of failure.

Example Flow : (using jsonplaceholder that is a fake API for testing and prototyping)
