Some processes not working from assistant after 2025.0.166 STS update

I am using UiPath Community Edition. Processes were working fine before the 2025.0.166 STS update. These processes work fine when run from studio but fail when run from assistant via triggers. They give “Could not find the user-interface (UI) element for this action”. I tried updating to latest package versions, deploying new build but no use.

Note: processes are working fine when run from studio.

Welcome to the community

  1. First keep some use logs messages and see exactly where it is failing
  2. As per error ui element not found occurs when no element or screen is found so check on the same
  3. May be in attended run the application might already be open we are not sure
  4. Is the unattended running on same machine or different?

Cheers

I am running the studio in same machine. I am having no issues in running studio but the package build of same process fails. I was having same issue with one element but when I removed computer vision from that element, unattended process detected it. Now am getting same error for another ui element in unattended run.

@sanket.nawaghare,

Check if the UI selectors are reliable and concrete to work in dev and prod as well.
Try to use simulate input method wherever possible as it

Hi @sanket.nawaghare

simply disconnecting and reconnecting using client id and client secret resolved the issue, allowing the processes to start successfully—this approach usually fixes similar connection or authentication problems.

If you found helpful please mark as a solution. Thanks
Happy Automation with UiPath

Hey @sanket.nawaghare many of the fellow member are facing that type of problem.as per the solution is go to orchestrator remove the machine and add that same machine again that it will generate client ID and client Secret copy that and paste it to the assistant where are you running your unattended bot. now your are good to go to run your process again. and before doing that if this happen in type into or any ui activity kindly enable the simulate/send window from the property panel of that activity.

cheers
