I have a new vm, Operating system Windows (Windows Server 2016 Datacenter).
When I try to enable backup and select new Recovery Service Vault, I get deployment error:

Deployment to resource group test failed.
Additional details from the underlying API that might be helpful: At least one resource deployment operation failed. Please list deployment operations for details. Please see <https://aka.ms/DeployOperations> for usage details.

**Resource**
vault242/Azure/iaasvmcontainer;iaasvmcontainerv2;test;web01/vm;iaasvmcontainerv2;test;web01

**Type**
Microsoft.RecoveryServices/vaults/backupFabrics/protectionContainers/protectedItems

**Status**
Conflict

**Status message**
{
"status": "Failed",
"error": {
"code": "BMSUserErrorContainerObjectNotFound",
"message": "Item not found"
}
}

Can't find any information for code BMSUserErrorContainerObjectNotFound and why a protected item not created automatically
