Thanks @ibersanoMS. Since the query now returns the microsoft.web/serverFarms resource type we'll need to update the recommendationResourceType in the yaml file and we should move the recommendation to the appropriate section in APRL. Recommendation's resources matching the recommendation resource type is a requirement for the new resource targeting feature coming to workload reviews in Advisor.

Let me know if you have any questions about these additional changes.
