TF Cloud with Azure - first time plan fails via github actions

Hello community,
I tried now various things for 20 minutes but I cannot get my first “github actions” which triggers a “terraform cloud run” to work.

I get the following error at the Plan stage of the run in terraform cloud (so far so good I suppose)

Error: building AzureRM Client: please ensure you have installed Azure CLI version 2.0.79 or newer. Error parsing json result from the Azure CLI: launching Azure CLI: exec: "az": executable file not found in $PATH.
│ 
│   with provider["registry.terraform.io/hashicorp/azurerm"],
│   on main.tf line 13, in provider "azurerm":
│   13: provider "azurerm" {

I don’t understand as the error would mean the CLI (worker vm ? right?) is or does not have azurerm installed or my terraform main is wrong which looks ok to me?
Totally at a loss currently :roll_eyes: and any help is appreciated

# Configure the Azure provider
terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "3.25.0"
    }
  }

  required_version = ">= 1.1.0"
}

provider "azurerm" {
  features {}
  version = "3.25.0"
}

resource "azurerm_resource_group" "rg" {
  name     = "myTFResourceGroup"
  location = "westus2"
}
terraform {
  cloud {
    organization = "myorgname"

    workspaces {
      name = "azure-playgroun"
    }
  }
}

When I ran the main.tf above locally (not using terraform cloud) the plan or deploy work fine.
Only when I use terraform cloud does the above not work (also from my ubuntu machine aka not using github actions).

I tried setting azurerm to version 3.0.0 also and again

 Error: building AzureRM Client: please ensure you have installed Azure CLI version 2.0.79 or newer. Error parsing json result from the Azure CLI: launching Azure CLI: exec: "az": executable file not found in $PATH.

terraform {

azurerm = {
source = “hashicorp/azurerm”

}
}
}

Configure the Microsoft Azure Provider

provider “azurerm” {
features {}
}

resource “azurerm_resource_group” “rg” {
name = “myTFResourceGroup”
location = “westus2”
}
