Hi all,

There is an issue in try/catch implementation.

I have configured the EXIT step as below in try block.

EXIT from - $parent

Signal - Failure

Failure Message - Error occurred.

But in catch block, i could not get the error by using get last error. The LastError doc is missing.

Can anyone suggest on this.

Hi Jacob,

please share the “Exit on” settings for the different sequences.
Might be that on of them has a wrong the setting for the Try/Catch-Senario.

Hi Holger,

Below are the EXIT ON details.

Seq (main) - Success
(try) - failure
(catch) - done

Use Exit on flow or Exit on loop instead of parent…

Exit on parent works little different, and you need to understand… If you use it inside the loop, it will work like, skip the current execution and continue with the next record in the loop.

Hi Senthil,

Thanks for the details. Below is my understanding of code.

Seq - (Exit on success)
Seq - ( Try - Exit on Failure)
MAP
Exit $parent and signal FAILURE (Error message)
MAP
Seq - (Catch - Exit on Done)
getLastError

So, when the control passes from Exit $ parent step, it should be coming to Catch block with the error details. Bu the IS is not considering it as an error and LastError doc is not present in pipeline.

Can you explain this behaviour?

Jacob,

Instead of
Exit $parent and signal FAILURE (Error message)

Set it as
Exit $flow and signal FAILURE (Error message)

You will see the way it works as expected by you.

Senthil,

Yes, EXIT $flow works. I just want to analyse when exactly EXIT $parent to be used.

Below is my observation.

Only when you want exit from a flow step without exception.

Also, getLastError will not catch the user defined exceptions in same flow service.

Jacob,
I will send you a working sample tomorrow when I get online again.

Hello Senthil,

Also, I observed that the “Timeout” property in flow step is not working as expected.

Can you share some working sample for timeout property in the flow steps please.

Hi guys, Im Kevin

I Also, Have doubted about what exactly going on
when I observed EXIT flow service with $parent. option.

look forward to get it clear, help me ~
