data variables must be four parts: data.TYPE.NAME.ATTR in: ${data.external.script}

[ghost]

This issue was originally opened by @JasonOliverEmaze as hashicorp/terraform#20586. It was migrated here as a result of the provider split. The original body of the issue is below.

---

Terraform Version

Terraform v0.11.11 + provider.external v1.0.0

Terraform Configuration Files

  program = ["python", "${path.module}/secret.py", "-id", "SFTP-Key", "-keyname", "private-key"]
}

output "Private Key" {
  value = "${data.external.script}"
}

Expected Behavior

I am hoping for the script to output the variable as it would be if the python script was run (stdout).

Actual Behavior

I believe I need to include an attribute such as ${data.external.script.*}, ${data.external.script.all}, etc.?

`Error: Error loading C:\Users\oliverj\Documents\Code\github\test\test.tf: Error reading config for output Private Key: data.external.script: data variables must be four parts: data.TYPE.NAME.ATTR in:

${data.external.script}`

Steps to Reproduce

1. terraform init
2. terraform plan or terraform apply
