Orchestrator Queues : Duplicates references with Unique References = Yes


We have a strange issue on our Orchestrator.
We have created a new Queue with Unique Reference = Yes.
On Studio, we have created a new workflow, with one Activity : add queue item, with reference = “test”

If we run several times this workfow, the add queue item runs perfectlu and add several transactions with the same reference key.

We attempt to see here an exception. Is it normal ?

UiPath 2017.1.6547

Kind regards,

Hi @fahuet

This is strange and is most likely a bug if everything is properly configured. Could you contact our support to help us track this issue?

I tested it on the latest 2019.2 and it works as expected, throwing an exception:

This is how my activity looks like:

And this is how it looks for me in the Orchestrator:

On top, this is our official documentation that confirms the behaviour should be correct on 2017.1:


Thank you for your answer.
We have several issues with Orchestrator 2017.1.6547.
We cannot upgrade it yet (we are dev team, and we didn’t have any hand on servers).

Kind regards,
