Long running workflow dependency issue

[Mark.Edgeller]

The Long Running Automation template creates with these dependencies:

If I try to change UiPath.BusinessProcess.Activities to UiPath.FlowchartBuilder.Activities, studio immediately hard-crashes.

Similarly, if I create a new project (not from the template) and try to add this package, this error occurs:

Hi @Mark.Edgeller , what version of Studio are you using for this? I’ve created a project from a Long Running Automation template and it creates it with the right dependencies - FlowchartBuilder and System:

What version Flowchart Builder did you try to install separately?

[Mark.Edgeller]

I’m on 24.10.12. I get the dependencies listed above in the OP.

Hi @Mark.Edgeller - thank you for the additional information.

Would you be able to share the feed for this template? We had removed the template from the Official feed a few weeks ago and the package isn’t one we officially support so I’m looking to understand how we can resolve this.

Many thanks,
Raluca

Hi @Raluca_Laic

It appears in the official feed for me:

This is located at the following:

Hi @Mark.Edgeller , thank you for flagging this, the template was an older version that we now removed to ensure we avoid this happening again.

For the other issue, would you be able to share with us what version of the FlowchartBuilder you attempted to install? There is one issue the team is investigating with older version of Studios but this error seems different - seems like it’s FlowchartBuilder v 1.0.1 based on the error.

If you have the possibility, I would recommend getting the latest STS version of Studio as it has a number of new capabilities in terms of Long Running Workflows:

Hi @Raluca_Laic,

I cannot remember which version I used at the time, and I’ve since cleared out the project. However, if I start a new project and add in version 1.0.4 from the Official package feed, then try to add an activity to the canvas, I get the following error:

The stack trace of the error is quite short:

Studio closed the active project due to a critical internal error. You may retry to open the project.

I assume from this there is some fundamental incompatibility with the version of studio I’m using. We are unfortunately tied to the Enterprise update ring, and I can’t simply go and download the current community edition.

If this is not fixable, its not a great problem. I simply wanted to explore Long Running workflows, as I think we’ll get a good amount of use out of it. I presume I can await the next enterprise version and this should work as expected?

Hi @Mark.Edgeller ,

This issue has been addressed in the 24.10.14 release and you should be able to create Long Running Workflow files after installing the Flowchart Builder package.

Just a quick mention, the version I was suggesting is still an Enterprise edition, it’s an STS version that gets updated more often.
