I'm trying to create an azure Redis instance at the Basic SKU. When I execute pulumi up, it fails because

"Code="InvalidRequestBody" Message="The value of the parameter 'properties.subnetId' is invalid."

However specifying a subnet ID is only available at the Premium SKU and gives this error if specified:

Message="Feature properties.subnetId requires a Premium sku to be set.

I'm not really sure how to get this to work at the basic tier. I've tired setting

PublicNetworkAccess: "Enabled"

, but still get the same issue
