Hi All! i have deployed a project (includes mail processing, OCR etc) in a QA server and everything works fine. i uploaded the same package to Prod Orchestrator and while running the process, the Robot gives the following error:
An error appeared while executing DACH_Return_Request_Processing_Prod
Error message: Cannot create unknown type '{http://schemas.microsoft.com/netfx/2009/xaml/activities}OutArgument({http://schemas.uipath.com/workflow/activities}BusinessRuleException)’.

bot the server configurations are the same. on analysing, i found out that the dependent packages for the project weren’t being downloaded. there are like 14 dependent packages, but only 2 of them are being downloaded along with the process folder.
i checked proxy, firewall etc and all the necessary URLs like for the orchestrator, nuget.org, gallery.uipath.com etc are whitelisted.
i tried to manually copy all the necessary packages from the QA machine and tried to run the process but yet it failed with the very same error. i am unable to find a solution for this. your help/ suggestions/ solutions highly appreciated. thanks!
