The plugin returned an unexpected error from plugin6.(*GRPCProvider).ValidateProviderConfig: rpc error: code = Unknown desc = got different PrepareProviderConfig #385

Describe the bug When performing terraform plan or terraform apply I get this error:

╷
│ Error: Plugin error
│ 
│ The plugin returned an unexpected error from plugin6.(*GRPCProvider).ValidateProviderConfig: rpc error: code = Unknown desc = got different PrepareProviderConfig
│ PreparedConfig response from multiple servers, not sure which to use
╵

To Reproduce Steps to reproduce the behavior:

  1. Create main.tf
terraform {
  required_providers {
    proxmox = {
      source = "bpg/proxmox"
      version = "0.22.0"
    }
  }
}
provider "proxmox" {
  insecure = true
}
data "proxmox_virtual_environment_version" "current_version" {}
output "version" {
  value = data.proxmox_virtual_environment_version.current_version
}
  1. Set environment variables
export PROXMOX_VE_ENDPOINT=https://192.0.2.1:8006
export PROXMOX_VE_USERNAME=root@pam
export PROXMOX_VE_PASSWORD=abc123
  1. Run terraform apply

Expected behavior

data.proxmox_virtual_environment_version.current_version: Reading...
data.proxmox_virtual_environment_version.current_version: Read complete after 0s [id=version]

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration and found no differences, so no changes are needed.

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

Outputs:

version = {
  "id" = "version"
  "keyboard_layout" = ""
  "release" = "7.4"
  "repository_id" = "46c37d9c"
  "version" = "7.4-13"
}

This behaviour only is exhibited when replacing the provider "proxmox" block with the actual credentials in the HCL.

Additional context Add any other context about the problem here.

Adding context, tested this morning;

variable "proxmox_username" {}
variable "proxmox_password" {}
variable "proxmox_endpoint" {}
provider "proxmox" {
  endpoint = var.proxmox_endpoint
  username = var.proxmox_username
  password = var.proxmox_password
  insecure = true
}

If I set:

export TF_VAR_proxmox_endpoint=https://192.0.2.1:8006
export TF_VAR_proxmox_username=root@pam
export TF_VAR_proxmox_password=abc123

This does work, so it's possible to load these variables from outside the provider, just not in the way that I'd expect.

Thanks for the report @JonTheNiceGuy!

Yeah, regressed when I added protocol v6 support and provider muxing as the first steps of migration to the new terraform plugin framework. Glad you found a workaround, but I'll try to fix it for the next release.
