provider.stdio: received EOF, stopping recv loop: err="rpc error: code = Unavailable desc = transport is closing"

[shimulch]

I was trying to run the example provided in this repository. I've made two changes (full file attached) -

• Upgraded jumphost version to 0.0.2
• Set password in provider configuration

But I could not run a successful terraform apply. Seems like the ssh tunnel getting closed before using it?

Terraform Version

Terraform v1.0.8
on linux_amd64
+ provider registry.terraform.io/hashicorp/http v2.1.0
+ provider registry.terraform.io/jaysonsantos/jumphost v0.0.2

Affected Resource(s)

Please list the resources as a list, for example:

• opc_instance
• opc_storage_volume

If this issue appears to affect multiple resources, it may be an issue with Terraform's core, so please mention this.

Terraform Configuration Files

terraform {
  required_providers {
    jumphost = {
      source = "jaysonsantos/jumphost"
      version = "0.0.2"
    }
    http = {
      version = "~> 2.1"
      source  = "hashicorp/http"
    }
  }
}

provider "jumphost" {
  hostname = "localhost"
  username = "terraform"
  port     = 2222
  password = 1234
}

data "jumphost_ssh" "httpbin" {
  hostname = "httpbin.org"
  port     = "80"
}

data "http" "example" {
  url = "http://localhost:${data.jumphost_ssh.httpbin.local_port}/get"

  # Optional request headers
  request_headers = {
    Accept = "application/json"
  }
}

output "host" {
  value = jsondecode(data.http.example.body).headers.Host
}

output "body_response" {
  value = jsondecode(data.http.example.body)
}
