Start by reproducing the issue from the azure-quickstart-templates/101-backup-oms-monitoring/ template: open the Azure Backup Monitoring Solution through Log Analytics and capture the failing query. Trace the query error mentioning the missing AlertSeverity_s expression, and consider the issue done when the solution opens without that BadArgumentError.
