Breakpoint reached document understanding

good everyone

I have a problem, I am using the document understanding activities, and when I use the present station validation activity, it randomly throws an error that “I have reached the breakpoint”

this error does not stop my process, but it is annoying to have to be clicking every time this problem comes out

I have tried the process without this activity and it does not give me these problems
I’ve checked if I have breakpoints in the workflow and there’s nothing there either

Someone who is throwing this error at me

thank you



You can check for Breakpoints by clicking on Show Breakpoint panel

If anything is present you can get to know, also if there is any exception also it will stop by error message

Enable Continue on Exception in the Debug panel

Hope this helps

Exact same issue here with the Present Validation Station and Present Classification Station. It happens about 3 out of 5 cases - sometimes even if processing a case it just successfully completed without that error
Exact error is: UiPath.SmartData.OutOfProcessUi.Host.WCF.exe - EXCEPTION

Breakpoint A breakpoint has been reached.

Image of error below - notice there are no breakpoints defined in this workflow either.

Do you still get the error? …

Definitely…as of yesterday night 7/25/2020.

I have the same issue. Did you find how to get rid of it?
I have displayed the breakpoint panel and deleted all the breakpoints but it still pops.

Thank you very much. FYI it even happens when running the workflow downloaded from the Doc Understanding Training course (which by the way is very good!)


Hi Ioana,
Do we have an answer about that?

Hi @borismh
We need a little more info to investigate this bug:

  • the OS you are using
  • the edition and version of your UiPath Studio (Home → Help, on the right side panel)
  • the version of the package UiPath.IntelligentOCR.Activities you are using (In the project panel expand Dependencies)
  • the version of the UiPath.CefSharpBundle dependency of the above package (In the project panel, expand Dependencies and the expand UiPath.IntelligentOCR.Activities . You will see UiPath.CefSharpBundle - hover the mpuse over it to see the resolved version image )

Also it would be great if you could share a workflow for which the issue appears for you.

I am encountering the same breakpoint error in some, but not all of my automations. Generally more likely to appear in dispatcher than performer. Using Windows 10,dependencies for one of the dispatchers exhibiting the error below. Work bots with proprietary information, so unable to attach, but can check different settings and let you know what they are. version of studio is 2019.10.3

Any progress on this? It is hanging up out ability to promote the bot to UAT or Production. Has anyone figured out a work around? Thanks

We tracked the root of the issue in a 3rd party dependency which is used in IntelligentOCR and in the Forms packages. We’ve updated the dependency and hopefully we’ll release it mid November.


Hi @warek

Just a final update, I believe the fix should have been live for quite some time. Updating your activity packages to the latest versions should fix the issue :slight_smile:
