Expected Behavior

Should be able to chain together other resources vs having to hardcode password

Actual Behavior

╷
│ Error: administrator_password is required when create_mode is Default
│
│ with module.mongo.azurerm_mongo_cluster.cluster,
│ on ../modules/mongo/main.tf line 7, in resource "azurerm_mongo_cluster" "cluster":
│ 7: resource "azurerm_mongo_cluster" "cluster" {
│
╵

Steps to Reproduce

1. terraform init
2. terraform apply

Additional Context

Works correctly if you hardcode the password as a string vs using a resource like random_password

Hello,

This appears to be an issue or question with the AzureRM provider, not with Terraform itself. You can see existing issues and file a new one in their repository here: https://github.com/terraform-providers/terraform-provider-azurerm/issues. If you have questions about Terraform or the AzureRM provider, it's better to use the community forum where there are more people ready to help. The GitHub issues here are monitored only by a few core maintainers.

Thanks!
