Error reading or replacing throughput from CosmosDB serverless database

[findemor]

Hello. I am trying to create cosmosdb database in a cosmosdb serverless account..
I am using azurerm version = "=2.29.0" with terraform cli v0.13.3.

When we create the terraform plan, it says:

Terraform will perform the following actions:

  # azurerm_cosmosdb_mongo_database.cm_db will be created
  + resource "azurerm_cosmosdb_mongo_database" "cm_db" {
      + account_name        = "dev-db-account-cm-ms-esb-custom"
      + id                  = (known after apply)
      + name                = "dev-cm-db"
      + resource_group_name = "custom-esb-automated-cm"
      + throughput          = (known after apply)
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Pay attention to line " throughput = (known after apply) ". I suppose this is the cause of the error..

When I apply the generated plan I get this error:

Error: Error reading Throughput on Cosmos Mongo Database "dev-cm-db" (Account: "dev-db-account-cm-ms-esb-custom"): documentdb.MongoDBResourcesClient#GetMongoDBDatabaseThroughput: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="BadRequest" Message="Message: {\"code\":\"BadRequest\",\"message\":\"Reading or replacing offers is not supported for serverless accounts.\\r\\nActivityId: 0c1498ff-e19e-42d3-hidden, Microsoft.Azure.Documents.Common/2.11.0\"}, Request URI: /offers, RequestStats: , SDK: Microsoft.Azure.Documents.Common/2.11.0"

  on main.tf line 97, in resource "azurerm_cosmosdb_mongo_database" "cm_db":
  97: resource "azurerm_cosmosdb_mongo_database" "cm_db" {

I suppose azurerm plugin is trying to read the throughtput value from azure, what is not allowed when using serverless cosmosdb.

Anyone is facing the same problem? Do you know some workaround ?

My cosmosdb terraform code (as you can see, I am not giving any value to troughtput, because doing that is not allowed in serverless -you get a completely different error message- which is logical):

## Data 

resource "random_integer" "ri" {
  min = 10000
  max = 99999
}

### CosmoDB Account
resource "azurerm_cosmosdb_account" "db" {
  name                = var.cm_cosmos_db_account_name
  resource_group_name = azurerm_resource_group.rg.name
  location            = var.cm_location
  offer_type          = "Standard"
  kind                = "MongoDB"
  enable_automatic_failover = true

  capabilities {
    name = "EnableServerless"
  }

  capabilities {
    name = "mongoEnableDocLevelTTL"
  }

  capabilities {
    name = "MongoDBv3.4"
  }

  consistency_policy {
    consistency_level       = "BoundedStaleness"
    max_interval_in_seconds = 10
    max_staleness_prefix    = 200
  }

  geo_location {
    location          = azurerm_resource_group.rg.location
    failover_priority = 0
  }
}

### Database Mongodb
resource "azurerm_cosmosdb_mongo_database" "cm_db" {
  name                = local.cm_db_name
  resource_group_name = azurerm_cosmosdb_account.db.resource_group_name
  account_name        = azurerm_cosmosdb_account.db.name
  depends_on = [azurerm_cosmosdb_account.db]
}

Thank you!
