[BUG]: failed to create OAuth token from GitHub App

[mattduguid]

Expected Behavior

that terraform plan would succeed

Actual Behavior

terraform plan failed

but if we pin back to an earlier provider version before https://github.com/integrations/terraform-provider-github/releases/tag/v6.9.0 it works fine, so that is our current workaround

Terraform Version

terraform versions tested, 1.13.5 on [CUSTOMER-A].ghe.com 1.14.0 on [CUSTOMER-B].ghe.com

Affected Resource(s)

• provider "github"

Terraform Configuration Files

provider "github" {
  alias    = "enterprise"
  owner    = var.ghe_owner
  base_url = var.ghe_base_url
  app_auth {
    id              = var.ghe_app_id
    installation_id = var.ghe_installation_id_enterprise
    pem_file        = file("${path.module}/../../modules/ghe/private.pem") # dynamically generated at runtime from gh secret on ephemeral gh agent
  }
}

provider "github" {
  alias    = "organization"
  owner    = var.ghe_owner
  base_url = var.ghe_base_url
  app_auth {
    id              = var.ghe_app_id
    installation_id = var.ghe_installation_id_organization
    pem_file        = file("${path.module}/../../modules/ghe/private.pem") # dynamically generated at runtime from gh secret on ephemeral gh agent
  }
}

Steps to Reproduce

terraform apply
