How to handle a HTTP request error (500)

[Marcello_Kera]

Describe the problem/error/question

I am constructing my workflow, but I need to handle a HTTP error (500) that the application I am getting information throws me when no data if found with some paramters.

In that case I want to perform a action to ad data.

But when its returns 500 the flow stops and never arrives on mu “IF” node.

What I shoud do?

What is the error message (if any)?

Hey @Marcello_Kera,

Did you enable the ‘Continue on Fail’ option from the setting tab of the node? It should look something as follow:

This would allow your workflow to continue, even if the HTTP calls returns in an error.

Great thanks, I didn’t know I had that option…
