"Error: port portion contains non-digit characters" Encountered When Using the TFE Provider

Problem

When executing Terraform configuration code that includes the use of the tfe provider, you encounter the error below during the plan phase:

Error: port portion contains non-digit characters
with provider["registry.terraform.io/hashicorp/tfe"]
on XXX.tf line X, in provider "tfe":
provider "tfe" {

Cause

• This occurs when the value for the hostname argument, or TFE_HOSTNAME environment variable set for use by the tfe provider, contains the scheme of an address, such as http:// or https://

Solution:

• Remove the scheme from the address that's set for the hostname argument, or TFE_HOSTNAME environment variable.

  • Example app.terraform.io or tfe.domain.com
