How do I destroy a module that has errors?

[yorinasub17]

I am trying to destroy a module, and am running into an error that is preventing me from destroy that appears to be a code issue. For example:

Error: Invalid index

  on .terraform/modules/server/modules/single-server/outputs.tf line 10, in output "public_ip":
  10:   value = var.attach_eip ? aws_eip.instance.*.public_ip[0] : aws_instance.instance.public_ip
    |----------------
    | aws_eip.instance is empty tuple

The given key does not identify an element in this collection value.Error: Invalid index

  on .terraform/modules/server/modules/single-server/outputs.tf line 10, in output "public_ip":
  10:   value = var.attach_eip ? aws_eip.instance.*.public_ip[0] : aws_instance.instance.public_ip
    |----------------
    | aws_eip.instance is empty tuple

The given key does not identify an element in this collection value.

Changing the attach_eip input has no effect. Is there anything I can do to destroy the resources in the state?

In some cases, you can avoid all code errors in terraform and trigger a destroy of all resources by creating a new empty module:

• Create a new module called empty with a single main.tf file that is empty.
• Ensure the empty module points to the state file of the module you are trying to destroy
  • If you are using terragrunt, update the terraform.source attribute in terragrunt.hcl to point to the empty module.
  • If you are using terraform, update the empty module to have a terraform.backend config that points to the state file of your original module.
• Now run terragrunt init && terragrunt plan (or terraform init && terraform plan). If you don't have nested providers (provider blocks nested in a terraform module call), this should create a valid plan to destroy all the resources. You can now run terragrunt apply or terragrunt destroy to destroy all the associated resources.
