local-exec provisioner for S3 bucket causes panic when used in a module

[2rs2ts]

When I have a module that creates an aws_s3_bucket and uses a local-exec provisioner I get a panic after the provisioning script runs.

Terraform Version

Terraform v0.7.8

Affected Resource(s)

• aws_s3_bucket
• module

Terraform Configuration Files

main.tf:

provider "aws" {
  region = "us-east-1"
}
module "mymodule" {
  source = "./module"
}

module/main.tf:

resource "aws_s3_bucket" "my_test_bucket" {
  bucket = "andrews-test-bucket"
  acl = "private"
  provisioner "local-exec" {
    command = "/bin/true"
  }
}

Panic Output

Expected Behavior

No panic should have occurred.

Actual Behavior

Terraform panicked after completing the provisioning. It created the bucket and ran the command just fine, but panicked afterward.

Steps to Reproduce

1. terraform plan
2. terraform apply

Important Factoids

This does not happen if the aws_s3_bucket is not created by a module, i.e. move the contents of module/main.tf into main.tf and remove the module declaration.

Also, this worked in 0.7.7. This is a regression.

Ah, this is fixed in 0.7.9
