I am building a workflow for invoice processing its work fine when I use present validation station. But now I am extend this process with “create document validation action” and “wait for document validation action and resume”.
In this stage I am getting bellow issues, please help me to resolve those.
for one invoice its working fine but it’s throw an error as below when go to pick next invoice [error scope for each(document) ]:
2.auto resume not working on workflow. It stucks as below image and not automatically resume (action center task performed as status : completed)
Hi @gpal :
On the second screenshot about studio showing that it is waiting on external events, is by design w.r.t developer experience . In this case developer has to go to ‘Actions’ in Orchestrator, complete validation and then come back to studio and click ‘resume’ because there is no way for Orchestrator to send a command to local studio/robot.
But in operational phase, ideally such processes will be deployed as un-attended process and at this point, job will be marked as ‘suspended’ freeing up the robot. As and one user completes the validation action, the jobs will auto-resume in the first available robot in the same environment.
Also if you are creating multiple actions, try to create all actions / read all documents , complete processing of other documents that does not require validation before invoking ‘wait and resume’ so that your workflow wont get suspended with every iteration.
Thanks,
Liji
There are couple of ways of doing it with in RE Framework. You should be straight forward able to invoke another orchestration process from RE Framework through start job for list of exception items that you want human to act on.
Embedding persistence activities within REFramework based workflow I would presume is again for scenarios where you have exceptions to be passed on to human for validation. You may have to be careful not to suspend workflow while processing each transaction, but identify all (bad)transactions that needs human action, create actions, add taskobject (actionsobject) to a list/collection but do not invoke ‘wait and resume’ immediately. Complete processing of all “good” transactions and then start a parallel for each to wait and resume (actionObject List) . One open issue here would be, if a queue item remains in ‘in-progress’ for more than 24 hours, Orchestrator will abandon this item. So need to be aware that end user in such cases have to act on such actions within 24 hours ( we are working on addressing this so that Orchestrator does not abandon such queue items waiting on human inputs)
You would want to look at sample snippets in studio (snippets > Orchestration) as well as refer to Orchestration Process
Related to the first issue: please check your variable scope. You might be overriding them from one branch of the parallel for each to the other, thus leading to inconsistencies and indexes out of bounds, etc.
can you please elaborate more about that? do you mean that i can first send all the invoice to action center at a time and after that it will vaidate one by one?
Hello Loana. In Uipath studio the updated packages of Integellient OCR and Document understanding ML and Omnipage OCR, which are causing weird issue in my process of invoice processing.
When I try to run English and Non-English Invoices together. For Non-English Invoices, I am getting fields are not captured and no single fields are extracted from the invoice in Present Validation station.
Then I have to manual capture each field from the Invoice. I have added proper taxonomy fields in Taxonomy Manager, I have trained invoice using Intelligent Classifier and selected proper fields in Data Extraction using ML Based extractor. It was not issue before updated version. All invoices were getting extracted in the Present Validation station.
The second issue is that, for the English invoices of similar type and same vendor are getting processed and most of fields data are getting extracted from the invoice in Present validation station. But if the invoice of different type and different vendor comes for processing in Present validation station, when process runs it halts and throws error in Present Validation station such as “Present Validation Station: The automatically determined extracted results references do not match the Document Object Model. They may have been created using a different Document Object Model.”. Please let me know proper solution this issue as well. I am sending you the error screenshot and process flow.
in for each loop,
i have Digitize document,
then write line
then classifying my doc
Present Classification Station
Train Classifiers Scope
Data Extraction Scope
Create Document Validation Action
Wait For Document Validation Action And Resume
then export result
all these activity works fine in first iteration, but in next iteration bot forget the files
it complete the first iteraction and exports the result for that document
now it again goes back to main for each loop where it have to take next document but it forget the value and gives this error
I’m looping through the files from directory in for each.
After first iteration , when second iteration reached “Data Extraction Scope” activity encounter this error. Not sure what is the issue behind.
Hi Ioana
Actually I’m working on document understanding but due accuracy issue facing lots of issues. Can you provide any learning resources on how can we use document understanding trainable model in AI Fabric and Use the ML Skill of the same in machine learning extractor in our document processing workflows and train the extractors accordingly .
I am getting the below error while using the Create Document Validation Action activity.
I think i have given Correct permissions to the robot to create actions into the Orchestrator still i am getting this error.
I have created a storage bucket using the Orchestrator itself. Please guide me on what am i missing here? I am facing this issue since a very long time now.

Yes. I am actually using the Community edition to try this out but unfortunately it gives me this error.
I have gone through a few discussions on this forum and they mentioned that its the issue related to the permissions and hence i have given all the permissions available to the bot. Still i get the above error.
Also in the “Create Document Validation Action” activity there is a property “Bucket Directory Path”. I have not mentioned any path there since i have created a Orchestrator storage bucket in the ‘Default’ folder. Is this the cause of the issue. If yes then please let me know how to determine the path.
Hi @Rajiv_Mulchandani : are you executing this workflow from studio? If yes, on the bottom right corner, it will show Orchestrator folder context . Please confirm if you have all the relevant permissions in this folder.
I am facing the same issue in For each loop, its not reading the second file in that folder after wait for document validation activity. Have you find the solution for this?
