Postgres example doesn't work with terraform 0.12.2 #134
Description
Environment
Terraform v0.12.2
provider.aws v2.15.0
terraform-aws-rds module version: 2.0.0
Problem
I attempted to run the example from here:
https://github.com/terraform-aws-modules/terraform-aws-rds/tree/master/examples/complete-postgres
with minimal changes (to use a smaller instance).
The plan step works fine, but the apply step fails with the following errors:
$ terraform apply main.tfplan
module.db.module.db_subnet_group.aws_db_subnet_group.this[0]: Creating...
module.db.module.db_subnet_group.aws_db_subnet_group.this[0]: Creation complete after 1s [id=demodb-postgres-20190620003555762500000001]
Error: Resource node has no configuration attached
The graph node for
module.db.module.db_parameter_group.aws_db_parameter_group.this[0] has no
configuration attached to it. This suggests a bug in Terraform's apply graph
builder; please report it!
