For files that are in Azure storage, ensure that you either use a SAS URI or assign an identity with permissions to view that file to the build VM by following the documentation here: [User Assigned Identity for the Image Builder Build VM](https://learn.microsoft.com/azure/virtual-machines/linux/image-builder-json?tabs=json%2Cazure-powershell#user-assigned-identity-for-the-image-builder-build-vm). Any file that is not stored in Azure must be publicly accessible for Azure Image Builder to be able to download it.
