Set transaction or postpone transaction failed from production server

HI, I’m trying to set transaction status to Success and passing output arguments like Status - In - OK. But I’m getting below error from orchestrator.

Method not found: 'Void UiPath.Orchestrator.Client.UiPathWebApi..ctor(Microsoft.Rest.ServiceClientCredentials, System.Net.Http.DelegatingHandler[])'.

Setting transaction to failed status is working fine without any error but setting transaction to success with output arguments always fails.

Note: If I try to set transaction status to Success without any output arguments then it working fine wihtout any exceptions.

Can someone suggest any fix for this or how we can avoid this error during robot execution ? Thanks in advance.


Were you able to solve this? I am getting the same issue when the process is published on Hypercare environment.

Thanks in advance for your help.
