Yet I have not used APIs with UiPath. But I was in need to integrate one service which is being discussed on the forum (Rossum Elis Data Extraction).
I was following instructions provided here (https://rossum.ai/blog/automating-data-extraction-from-invoices-using-rossum-api-and-uipath/) that seem pretty straightforward.
I signed up for an API authorization key and assigned uploadEndpoint = “https://all.rir.rossum.ai/document” , as it stated in specification.
After i launched the robot it failed at the Extract ID activity inside Upload State, saying "Extract ID: Object reference not set to an instance of an object " .
Investigating it i understood that HTTP request activity which output is ResultJSON came in empty.
I tried Rossum’s template PDF which i found here (https://github.com/rossumai/elis-client-examples#example-data) to understand if it fails with my PDFs only but, alas, it did not succeed as well.
Is there any workaround in that case?
Just in case here’s xaml file RossumUIPath.xaml (56.8 KB)
