This article describes how to use Bicep and a deployment script to pause a deployment in order to wait for a resource property to return a specific value. You can use this technique to ensure that a deployment succeeds when the resource that's being deployed reports to Resource Manager that it's ready but the underlying resources aren't. When this happens, the resource that's being deployed isn't yet ready to interact with the remainder of the deployment, so a pause is required.
