The exception is in there. Did you try to resolve this?

I tried by allowing folder permission by granting write access

but still issue is same

The issues seems to be there, unless you are running a background process, this error should be a clear issue related to the folder permissions not being set up correctly.

You can use a different folder location perhaps? Personal folders are a bad idea in my opinion unless it an attended automation, and those should be dynamic.

Your workflow is trying to create or write inside a folder:

C:\Users\HP\Documents\UiPath\GST_Automation - Copy\GST_Automation_Logs

When running from Orchestrator, the bot does NOT have permission to access your local user folder (C:\Users\HP\…).
So UiPath throws:

UnauthorizedAccessException – Access is denied

This only happens in Orchestrator, not in Studio, because the robot runs under a service account, not your Windows user (HP).

Instead of writing inside C:\Users\HP..., write to a folder the robot always has access to, for example:

C:\UiPath_Logs
D:\RPA_Logs\

Update your workflow to use this new path.

Your bot cannot access the folder because Orchestrator robots run with different permissions. Change the folder location OR give proper access rights to fix the issue.

Hi @Prabhakaran_Elango

As per my understanding , error due to unauthorizedaccessException → folder path access denied. try to give write permission to that folder → run workflow again. or try to create a data folder under the same UiPath folder.

happy automation
