!!!!!!!!!!!!!!!!!!!!!!!!!!! TERRAFORM CRASH !!!!!!!!!!!!!!!!!!!!!!!!!!!!

Terraform crashed! This is always indicative of a bug within Terraform. A crash log has been placed at "crash.log" relative to your current working directory. It would be immensely helpful if you could please report the crash with Terraform1 so that we can fix this.

When reporting bugs, please include your terraform version. That information is available on the first line of crash.log. You can also get it by running 'terraform --version' on the command line.
