• The commented ESRP task references undefined variables ${{parameters.ArtifactName}} and ${{artifact.name}} on line 73. These parameters don't exist in this template's parameter list (only NameForReservation and VersionForReservation are defined). This will cause errors when the task is uncommented. Based on the context, the FolderLocation should likely reference the corrected esrp directory path and use ${{parameters.NameForReservation}} instead.

from what I understand lgtm, is this triggered in CI when a new package gets merged to main?
