Debug Output/Panic Output

Vault Name: "rsv-backup-test"): performing CreateOrUpdate: unexpected status 400 with error: UserErrorUnsupportedVaultImmutabilityStateChange: The immutable vault property for this vault is locked, hence, this setting cannot be disabled. The vault has its immutable vault property enabled and locked, and it can no longer be reverted to a non-immutable vault. Refer to the documentation to learn more: https://aka.ms/AB-ImmutableVaults-States

Expected Behaviour

Recovery Vault is created

Actual Behaviour

No vault is created and error is thrown

Steps to Reproduce

terraform init
terraform apply

It is not a terraform issue but one of the Azure CLI. It can also be reproduced running the command:
az backup vault create --location eastus --name rsv-backup-test --resource-group rg-backup-test --immutability-state Locked

The workaround is to create the vault first unlocked and then reapply the configuration with the vault locked. Documenting here so it can be linked to a Microsoft API issue, thank

Hi @davepattie, thanks for reporting.

per tesing, the immutability can not be directly set to Locked from Disabled, and it acts as same as Portal, which I personally assume it's by design. I have submiteed a PR to let terraform manage this correctly (#23806). Once it merged it should work fine.

Thanks!
