Publish Button In Studio Is Grayed Out

Why is the Publish button grayed out in Studio ?

This is an expected behavior as Attended Robots are designed for debugging (& running) purposes only. Refer the Licensing documentation . However, below alternate methods can be used -

  1. Try publishing the workflow to a local directory and upload the resultant .nupkg file in Orchestrator directly (Packages page).
  2. Change the Robot type to Development/ Studio from Orchestrator. Make necessary changes to the workflow and publish it to Orchestrator. Once done, update the package version in Orchestrator. At that time, change the Robot type back to Attended.
