Region Mismatch Error Between Cloud Volumes ONTAP and Custom Azure Key Vault

• BlueXP Connector
• Working Environment (WE)
• Cloud Volumes ONTAP (CVO)
• Custom Azure key vault

• When creating a new Working Environment using API call and disk encryption with custom key vault, the deployment fails with error that CVO and Vault region doesn't match:

{ "message": "Azure CMEK supported only when the CVO and the vault in the same region. CVO region: uksouth. Vault region: UK South", "causeMessage": "BadRequestException: Azure CMEK supported only when the CVO and the vault in the same region. CVO region: uksouth. Vault region: UK South" }

• If CVO region is manually set to UK South in deployment JSON file:

BlueXP will fail to find valid configuration for specified ONTAP version:
