Hi all, I create some BP widgets using VaRest plugin. All are working, but I don’t know how to test if there are active connection or not, or server errors.
The BindEvent on RequestFail never fire, if I rename or delete my php page, or set a inexistent url, I don’t get any fail notification.
I tried with CallUrl, and in Callback I check if IsValid Json, so I could at least print a error message…
Here I tried ExecuteProcessRequest, in this case EventFail fired, but immediatly UE crashed.
Please can someone help me for check connection before load php page, or check if the response fail?
Thanks

About VaRest - don’t use Call URL, it’s the wrong way of doing it (Not always! But mostly it’s a wrong node to use)
Whenever you get a response from the Server - you can pull it out and find “Get response content as String” to see the result - it will also show errors so you don’t need the “on failed” Event
You can get from the Response “get String Field” with name “error” - if string is empty = no error, if not empty - show the message (so use a branch here)
Also here’s a visible example of what I mean
I just saw this post is from 2 years ago, so I thought I will mention you so you will see my answer ;]
