Studioで作成したプログラムをCloud Orchestratorを利用してUnattended Robotで実行しようとしたところ下記のエラーが発生しました。

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

   at RMS_売上集計.Main.GetImplementation()
   at System.Activities.Activity.OnInternalCacheMetadata(Boolean createEmptyBindings)
   at System.Activities.Activity.InternalCacheMetadata(Boolean createEmptyBindings, IList`1& validationErrors)

   at System.Activities.WorkflowApplication.SimpleOperationAsyncResult.Run(TimeSpan timeout)
   at System.Activities.WorkflowApplication.BeginRun(AsyncCallback callback, Object state)
   at UiPath.Executor.RobotRunner.RunWorkflow()

なお、バージョンは以下のとおりです。
Studio：23.8.0
Unattended Robot：23.4.4

以下の事象と類似しているかと思いますが、解決した報告が入っていないようで対処方法についてご教示いただけないでしょうか。

こんにちは

ロボットのバージョン前方互換性は担保されませんので、基本的にはまずは

StudioのバージョンをRobotに合わせて、プロジェクトを作成しなおす
または
RobotのバージョンをStudioにあわせるかそれ以上にする

方が良いかもしれません。

互換性については下記参照ください

Hi @tlunlun09

If you are using any package which is higher than any available in Enterprise version then it won’t work. Don’t use beta versions in Enterprise versions. If you lower the versions available to match with Enterprise and publish, it will work.
Uninstall community version studio and install Enterprise dev studio and link with that Enterprise cloud orchestrator to resolve the issue. Enterprise studio is 2023.4.4.

or try checking below things first.

  1. We should have any on going connections with the VM(bot machine) like user logins. to avoid this we have to restart the VM to make sure that no user logged into this VM machine.
  2. Have you installed the Bot which you are running as un attended from orchestrator by using MSI installer since we must install the bot with service mode since service mode bot is required for un attended automation.
  3. Make sure that you assigned un attended bot license for the Bot(VM) which you are trying to run your process un attended.
