Azure VM Cross-Region Restore from Recovery Services Vault(RA-GRS) Snapshot

- **Darwin Kernel Version 25.4.0**:
- **Python 3.14.3**:

**Describe the bug**
Primary Region -- Resource Group and a VM that is BackedUp in Vault Recovery Services configured with RA-GRS, Creating a VM in Secondary Region using the Backup fails with the SDK.
**To Reproduce**
Steps to reproduce the behavior:
1. Ensure Secondary Region(Target Infra -- ResourceGroup and Vnet/Subnet) is in place to Restore a Backup and create a VM.
2. Locate Backup Container and Protected Item in Primary Region(Source Infra - ResourceGroup, VaultName and SourceVMName) -- Container_name and Protected_Item_Name
3. Identify Latest Recovery Point and Identify Disk Metadata if available
4. Trigger cross-region restore job with `RecoveryServicesBackupClient`

```

bc: RecoveryServicesBackupClient,

vnet_id:str,
vault_rg: str,
vault_name: str,
container: str,

target_rg: str,
target_region: str,
subnet_id: str,
storage_account_id: str,
):
"""

"""

restore_request = IaasVMRestoreRequest(
recovery_type=RecoveryType.RESTORE_DISKS,
target_resource_group_id=(
f"/subscriptions/{sub_id}/resourceGroups/{target_rg}"
),

virtual_network_id=vnet_id,
subnet_id=subnet_id,
original_storage_account_option=False,
# disk_encryption_set_id=None, # uncomment + set if using CMK
)

log.info(
f"Submitting cross-region restore job ...\n"
f" Vault : {vault_name}\n"
f" Item : {item_name}\n"
f" RP : {rp_name}\n"
f" Target : {target_region} / {target_rg}"
)
return bc.restores.begin_trigger(
vault_name=vault_name,
resource_group_name=vault_rg,
fabric_name="Azure",
container_name=container,
protected_item_name=item_name,
recovery_point_id=rp_name,
parameters=restore_request,
)
```

**Expected behavior**
A VM in Secondary Region(target_region and target_rg) needs to be provisioned using the backup identified by RecoveryPoint.

**Screenshots**

**Additional context**
Additionally Tried Fetching the RecoveryPoint from Secondary Region using the filter:
`filter_string = "use_secondary_region eq 'True'"`
Same issue.
Also tried using REST endpoint for RecoveryPoints with the above filter and multiple compatible api-versions same error
