populating details for %s: `model.Properties` was nil

Error message

populating details for %s: `model.Properties` was nil

What it means

populateAccountDetails (storage_client_helpers.go:124) dereferences account.Properties to read IsHnsEnabled and the primary endpoints. If the StorageAccount response from ARM has a nil Properties, there is nothing to read and the helper aborts defensively.

Solutions

1. Retry; if persistent, inspect the raw GET response for the account.
2. Confirm the storage account exists and the identity can read it.
3. Update terraform to a version whose Azure SDK matches your cloud.
4. If it recurs, report the account ID and ARM response to maintainers.

# confirm the account returns a Properties object
az storage account show --name <acct> --resource-group <rg> \
  --query "properties" --output tsv | grep -q '.' \
  || echo "WARN: storage account Properties is empty"

// guard populateAccountDetails against a nil Properties
func hasProperties(a storageaccounts.StorageAccount) bool {
    return a.Properties != nil
}

When it happens

Trigger: ARM GET on the storage account returns a model whose Properties field is nil, which the populate function cannot process.

Common situations: API-version skew between the bundled go-azure-sdk and the cloud; partial or error responses; sovereign/private cloud returning a reduced shape.
