module.db.aws_db_subnet_group.db_subnet_group: "name": required field is not set

[dgolja]

Hi there,

Terraform Version

terraform -v
Terraform v0.9.2

Affected Resource(s)

• aws_db_subnet_group

Terraform Configuration Files

resource "aws_db_subnet_group" "db_subnet_group" {
  name_prefix = "something"

  subnet_ids = ...
  tags {
     ...
  }
}

Expected Behavior

When trying to run terraform plan I was expecting that the plan will show the aws_db_subnet_group creation, however I get a unexpected error.

Actual Behavior

I get the following error:

* module.db.aws_db_subnet_group.db_subnet_group: "name": required field is not set
* module.db.aws_db_subnet_group.db_subnet_group: : invalid or unknown key: name_prefix

Based on the documentation name and name_prefix are optional, however the error implies that name is required and name_prefix is invalid.

Steps to Reproduce

1. terraform plan
