For branch versioning, you can use a feature service URL (that is, https://mysite.mydomain/server/rest/services/ElectricNetwork/FeatureServer) or a feature layer portal item. You can also delete a branch version using a database connection file (connected to a branch versioned workspace) when connected as the geodatabase admin user (sde).

For branch versioning, if the input workspace is a database connection file, the name of the branch version to delete should be fully qualified (for example servicename.portaluser.versionname). If the input workspace is a feature service URL, the name of the branch version to delete should not include the service name (for example. portaluser.versionname).
The updated input workspace.
