Debug Output/Panic Output

│ Error: `source_server_id` is required when `create_mode` is `GeoReplica`
│
│   with module.azure_mongodb_cluster["mongo-replica-01"].azurerm_mongo_cluster.replica[0],
│   on ../../modules/terraform-modules-azure/modules/azure-mongodb-cluster/resource.tf line 28, in resource "azurerm_mongo_cluster" "replica":

Expected Behaviour

The replica mongodb_cluster should be created after the primary instance is created.

Actual Behaviour

Create fails because the primary cluster id can not be fetched from the state.

Steps to Reproduce

Run the provided code using terraform apply
