UiPath -Error {“message”:"Click Text 'SAPTreeList': Cannot find the UI element corresponding to this selector: <wnd ctrlid='90279688' />

I am following the video SAP Automation with UiPath to automate login as a user with valid credentials within a SAP Server.

SAP Information: IDES ECC 6.0 incl. EhP7

The login process as per the tutorial basically works for an hour or so since it’s creation. But whenever I am trying to execute the workflow after long intervals (example, next day), the robot won’t start and I am facing an error as:

Studio.log:

Any pointers where I am going wrong?

Hi @debanjan

Any chance you are working on a virtual machine that has a policy to reset the environment ever so often?

@loginerror Thanks for your attention. Nopes, I am not on any VM. I use a Intel Core i3 CPU with 64 bit - Windows 8 system. Any ideas where things are going wrong?

@debanjan Just try this Create a new project folder and delete the main file from created project folder than paste your main file which you are getting error to newly created project folder

@indra Thanks for your attention. I have tried the step you mention so many times. All the other SAP workflows (Desktop Recording within a flowchart), individually or as a part of a flow works just perfecto. Only this individual flow is having the issue.
