   I hit the same warning on a Flex Consumption app with a system-assigned identity and AzureWebJobsStorage__blobServiceUri / __queueServiceUri / __tableServiceUri configured.

   Cause: resourceValidator.ts only checks AzureWebJobsStorage and AzureWebJobsStorage__accountName, in both getFunctionappSettingsRbac and getFunctionappSettingsScm. On Flex the settings are never read (deploy goes through Kudu api/publish), so the warning is cosmetic there. On the run-from-package path it is a real bug, though: websiteRunFromPackageDeploy.ts builds https://${AzureWebJobsStorage__accountName}.blob.core.windows.net, which becomes https://undefined.blob.core.windows.net when only the URI-based settings exist.

   I opened #408 with a fix: any non-empty AzureWebJobsStorage__* setting now counts as configured host storage, and the publisher uses AzureWebJobsStorage__blobServiceUri when present (falling back to __accountName), with a clear error if neither is set.
