Below is the error :

Also, I have a query reagrding how to configure the Server Endpoint in this activity.
@TimK Thanks for your help. I’m able to progress on that. Just have one more query, can you tell me how does this activity function and how can we extract values from pdf using this extractor?
This gives you a good oversight of the activity and includes a demo.
It works by using the IntelligentOCR built by UiPath to access the document and retrieve key words you have identified. It the learns based of of more documentation you put through it through the validation station.
I have gone through the link and was following this link for doing this document. But I’m not able to understand how we check the extracted output and how the values are getting extracted and where they are getting stored.
How to create API key for Machine learning extractor using on premise orchestrator account.
Error -
Data Extraction Scope: Request is unauthorized. Please make sure that a correct API Key was provided.

Go to platform.uipath.com and access your account. Then go to the Licenses tab from the left hand menu, look under the Document Understanding entry, and you should have an ApiKey auto-generated in there. You can copy it from the Copy button and paste it between quotes in the activity directly.
Hi, I have the same issue. Did you already solved this, and if yes, how? I face the same problems. My Studio is connected to the UiPath Cloud Plattform, and when I use these API-key for Document Understanding I receive the same error.
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
If you have a use case that is not in the list of our pre-trained available models, consider building your own
Use AIFabric and the DU ML packages to define and train your own model based on your needs.
Pls reach out to your UiPath contact to see how to get access + access to DataManager for document tagging (tagging documents to have the data on which the model can be trained).
Please check you are not overwriting your variables - if the exception appears for the file path, check you are not using the same variable to capture something else in your for each.
Also pls note you should be using a parallel for each instead of a for each if you don’t want your process to run sequentially and stop and wait after each single document. Do ensure that all variables specific to one file are only within the scope of the parallel for each / for each loop…
I also strongly suggest you activate the Log Activities button in your Studio (Debug tab) to see which activity it reaches, where it crashes), and using the debug file feature, to see the state of your variables when the exception occurs . This would make your life easier
