Hello Everyone,

I have a regarding a package which is being published to orchestrator using azure devops pipeline. I have created the pipeline and its job is to build a package everytime and publish it to orchestrator with the new build. Thats perfectly working but after the package gets published, i cannot start the process from orchestrator. I am getting the following error:

Could not load type ‘System.Activities.TextExpressionBase`1’ from assembly ‘UiPath.Workflow, Version=6.0.0.0, Culture=neutral, PublicKeyToken=null’.

System.TypeLoadException: Could not load type 'System.Activities.TextExpressionBase1' from assembly 'UiPath.Workflow, Version=6.0.0.0, Culture=neutral, PublicKeyToken=null'. at PDE0003_GlobalStoreManagement_Performer.Main.GetImplementation()** **at System.Activities.Activity.OnInternalCacheMetadata(Boolean createEmptyBindings)** **at System.Activities.Activity.InternalCacheMetadata(Boolean createEmptyBindings, IList1& validationErrors)

interestingly if i publish the version directly from studio to orchestrator instead of using the pipeline then i cant start the process and everything is fine.

I need to run it through pipeline since it is the requirement. Untill now I have compared dependencies and checked the compatibility with orchestrator there everything looks fine. Can someone help me further with this ?

Thanks in advance

Hi @tarif.mohammad

Uninstall the studio and then install it form orchestrator and try publishing the code then and it should work!!

The studio version is higher than the orchestrator version and it’s the reason for the error so please follow the steps said before and it works!!
