Hi All,

my studio just updated today to 2019.10.3 and after I opened my previously working project. It is now displaying a validation error. My project has dependency on my other UiPath Library Projects named OdysseyLibrary. It Used to work with no errors prior to the update.

Validation Error:
Issuance.xaml: System.NullReferenceException: Object reference not set to an instance of an object.
at OdysseyLibrary2.NewReceipt.GetImplementation()
at System.Activities.Activity.OnInternalCacheMetadata(Boolean createEmptyBindings)
at System.Activities.Activity.InternalCacheMetadata(Boolean createEmptyBindings, IList1& validationErrors) at System.Activities.ActivityUtilities.ProcessActivity(ChildActivity childActivity, ChildActivity& nextActivity, Stack1& activitiesRemaining, ActivityCallStack parentChain, IList1& validationErrors, ProcessActivityTreeOptions options, ProcessActivityCallback callback) at System.Activities.ActivityUtilities.ProcessActivityTreeCore(ChildActivity currentActivity, ActivityCallStack parentChain, ProcessActivityTreeOptions options, ProcessActivityCallback callback, IList1& validationErrors)

at System.Activities.Validation.ActivityValidationServices.Validate(Activity toValidate, ValidationSettings settings)
at System.Activities.Presentation.Validation.ValidationService.CoreValidationWork(ValidationReason reason, CancellationToken cancellationToken)

Would appreciate if anyone can explain why I’m getting this new error, thanks.

Greetings, I have a sudden error that is halting a lot of work so I’m writing this in a panic.
Yesterday a process that we run every 15 minutes suddenly stalled after it couldn’t get a valid asset from Orchestrator as a result a 1 day worth of jobs stacked up. During this we had 20 long running processes going and after terminating the stalling job all of those long running process faulted immediately after they tried resume. and now all long running process I start fault after trying to resume. I’ve tried multiple versions of the long running processes and tried running them locally on my machine and it works fine on my machine.

I write this in hope that this is some problem on orchestrator’s end that is being fixed or is easy to fix

Thanks in advance
Sincerely Hallgrímur

Hi everyone,

I am trying to take screenshot from mainframe terminal.

1. The code is working fine when I’m running it from the studio.
2. The code is working fine when running from the agent only when the daas machine is open. If the daas machine is minimised the screenshot activity is not taking the screenshot.
3. The code when deployed to orchestrator is working sometimes and it’s not working sometimes.

Can anyone please help me solve the issue, I’m working on an urgent deployment.

Regards
Priya

Hello,

I am currently facing issues with a process that runs off a partitioned VM, and I cannot work out why the process does not work. It is a client VM so I can’t change any of the resolution settings, or find out what they are. The process runs fine on physical machines, but does not work off the partitioned VM.

Has anybody else faced unknown issues with a partitioned VM? If so, what did you do to resolve the issues? Any feedback is appriciated.

Thanks in advance!

Hello All,

I’ve just started with going through tutorials on Academy. On trying to run my first sequence I got an error “Cannot acquire a license”. I’m using the Community edition of Studio, where the license is set up for my organization. When I click on Tenant -> Users in Orchestrator, I see that Robot Access is “enabled” and License Type is “inherit from user’s organization”. On looking through the documentation, I see that the license needs to be activated and a license activation wizard was supposed to be started on opening Studio for the first time. This did not happen for me.
What can I try to resolve this error?

Thank you,
Yury

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

Hi all,

I have developed a bot that clicks on certain images on screen and it works fine in my desktop for all kind of inputs. But when i try to run the same bot in a different system its not able to identify the images that appear on screen.

**The selectors for the click activities are valid in both the systems the error that comes is image nor found, even if its present in screen.

**The font remains the same in both systems yet its not identifying them. When I re-capture the image from second system it works.

Can some one let me know why, image activities like click image image exist on image vanish etc… do not work on other systems. it would be difficult then to run the bot on different systems.

Thanks in advance

Hi Community,

I am trying to extract invoices from ACME webpage. Any idea what I am doing wrong implementing Extracting Structured data?

image1888×1008 74 KB

Wouldn’t it be better to use data-scrapping activity instead?

Here’s my selector:
<html app='chrome.exe' title='ACME System 1 - Search Results' /> <webctrl tag='TABLE' />

Hi,

I’ve been trying to build a document understanding framework using regex for invoices. For each supplier I add a new document type. Now I got 19 supplier with all the regex expressions in place.

When I try to add a new supplier, the error icon pops up on the Configuration field in de input properties.
I can’t see what the exact error is because the string in de Configuration field is very long.

Is there a limit in how long the Configuration property can be and so is there a limit how many document types you can add?

I tried to debug so that I was able to export the output and in the txt file I see ‘Line is too long’. But I’m not sure if the output error is to long to mention, or that ‘Line is too long’ is exactly the error.
