It appears you’re encountering an error related to the UiPath Document Understanding service. The error message indicates that the API version being used is incorrect. The service expects the API version to be ‘1.2’, but a different version is being sent.

It could be due to UiPath.IntelligentOCR.Activities package compatibility.
Check the compatibility of the all package versions with this one.

Thanks for the prompt reply.

As suggested, I made the changes but still facing the same issue. I have already tried to upgrade/Downgrade the UiPath.IntelligentOCR.[Activities] package compatibility but no luck. I guess somehow issue is related to API Version.

Is there any solution to rectify the issue. FYI, also upgraded the .NET Framework to the latest.


I tried to search for the documentation regarding this but nothing I found.


Could you please redirect this to someone who can help here?
