    "incantation": "When provider source or version requirements need values supplied as constants or locals, reference them in `required_providers`; keep variable values independent of dynamic plan results. Supply const-variable values at plan time with supported methods such as `-var`, `-var-file`, or environment variables.",

      "terraform {\n  required_providers {\n    random = {\n      source  = \"app.terraform.io/${var.organization}/random\"\n      version = local.random_version\n    }\n  }\n}\n\nvariable \"organization\" {\n  type  = string\n  const = true\n}\n\nlocals {\n  random_version = \"3.9.0\"\n}",
