Get Exception Type of Queue Item

[Shreya_Rao1 (Shreya Rao)]

Hi,

Is there any way to get the type of Exception from Queue Items?
Like for example from below Queue item I need to know that Queue failed due to Application exception of business Exception

Hi @Shreya_Rao1
Hi,

you can now access processing exception as well directly from a queue item variable.
in this example is used GetQueueItems and just got the first one, but using a loop should not be a problem.

Cheers

I tried using Processing Exception function, but using that I get the message assigned with that failure not the type of Failure i.e whether it is “Business” or “Application”

[marian.platonov]

Did you try using a Rest API call for that?

[Shreya_Rao1 (Shreya Rao)]

no but cant we do without using api?

[raja.arslankhan (Raja Muhammad Arslan khan)]

@Shreya_Rao1 Have you try this one?
You can set the details of the exception with Set Transaction Status. You can later fetch those details with MyQueueItem.ProcessingException.Details , where MyQueueItem is a QueueItem object.

In the UiPath API / implementation we do have an ENUM: ProcessingExceptionType

This ENUM has two forms: ApplicationException, BusinessException

similar what do see in short in Orchestrator Table

An Access can be done by:
YourQueueItemVar.ProcessingException.Type

More detail information on which detail Exception occurred we can retrieve by
YourQueueItemVar.ProcessingException.GetType
(System.Exception, SelectorNotFoundException…)

Kindly note:
when the QueueItem was not failing then the YourQueueItemVar.ProcessingException is NULL.
In such a case, access would result in the typical Reference not set… Exception

So we would check in advance with isNothing(YourQueueItemVar.ProcessingException) if it is null or not. If it is set then we access as described above.

@Shreya_Rao1

no but cant we do without using api?

so with already mentioned Get Queue Items (maybe with additional set filter options) then QueueItems can be retrieved and evaluated / postprocessed with:

• for each
• LINQ
  …

depending on what is needed. By the Processing with we check defensive if the ProcessingException is set or not (as described above) before accessing its Properties / Methods.

Also note:
When setting e.g. the status on a QueueItem (e.g. with Set Status activity) and later in the flow, the MyQueueItem.ProcessingException is accessed it will be always null also when the QueueItem failed and the status was set.
There is no Round-Back / Refresh on the local QueueItem variable and therefore we cannot refer to the ProcessingException.

Discussion in the Feedback Category here:

Feature request: Queue Item - Refresh method

lets have an activity or API Method for refreshing a QueueItem e.g. after setting Progess Yes we can do it with available option like get QueueItems and reference filter or ORC API But it will be easier to have it offered by a dedicated option

Hi Shreya,

I came accross this open conversation with no solution marked so gave a thought to share it with you.

Simply use GetQueueItem activity, its output you will get QueueItem.
use for each loop activity of TypeArgument QueueItem
inside which use log message “QueueItem.ProcessingException.Type” it will give you result ApplicationException or BusinessException.

or else you can also below command if you dont want to use for each loop and check the latest on top exception.

QueueItem.First().ProcessingException.Type
