So to start off I’ll mention that currently I am on a trial version with everything working on UiPath cloud products, no on prem currently. I am testing out the document understanding capabilities but I keep getting these two vague errors:
(A timeout error and a 503 service unavailable error)
Timeout:

503 error:
UiPath.DU.Shared.DuAppClient.DuAppException: DuApp server returned 503 (Service Unavailable). Additional details: no healthy upstream at UiPath.DU.Shared.DuAppClient.DuAppClient.PerformGet(String url, CancellationToken cancellationToken, Nullable1 timeout) at UiPath.DU.Shared.DuAppClient.DuAppClient.GetModelFields(Skill skill, CancellationToken cancellationToken, Nullable1 timeout) — End of inner exception stack trace
The automation is very simple but here are some screenshots if that helps:
The error is occuring during the “Extract Document Data” step.
I’ve seen a lot of similar questions with answers about the desktop or on-prem version of many of these tools so I want to remind again that everything here is on cloud.
Edit: I had to remove some screenshots because I am only allowed to post one I guess (?)
