See below for a few examples of the App Studio publish guardrails:

• App Studio can only publish if there is one configured deployment pipeline in Deployment Manager. App Studio returns an error if you attempt to publish with more than one deployment pipeline configured.

• If you have no pipelines configured, App Studio returns the following error. To add a pipeline in Deployment Manager, see Creating pipelines.
  
  

• It is not recommended to have a manual transition configured in your deployment pipeline. If a manual transition is required, you can configure this at the stage level. Once the stage encounters the manual transition (after all tasks complete in the stage), the Action Required alert is displayed on App Studio. You must switch to Deployment Manager to manually promote to the next stage.
  
  
  • If there is any manual input or approval needed between tasks for the deployment to proceed, you can configure the Perform manual step task in the pipeline. If the deployment is waiting at Perform manual step, you can approve directly from App Studio through the Perform manual step link.
  • 
    

• If a publish is paused, the pipeline will reflect that status with a Publish paused warning on in the stage on which it paused. To resume publication from the paused state, contact your application administrator.
  
  

• If a task fails for any reason in the publish cycle, the application publish will stop. The pipeline model provides a error for the stage on which Publish failed, along with the list of failed tasks to remedy before attempting to publish your application again. Once the issue is resolved, contact your application administrator to access Deployment Manager and retry the failed task and resume publishing.
