terraform バージョン 13 で、リージョン パラメータの変数のデフォルト値が無効であるというエラーが発生します。これを修正するにはどうすればよいでしょうか?

./terraform0.13 初期化 - 再構成

There are some problems with the configuration, described below.

The Terraform configuration must be valid before initialization so that
Terraform can determine which modules and providers need to be installed.

Answer 1

us-central-1 に設定してみてください。リージョンのフォーマットが間違っているので、数字の前にダッシュが必要です。また、terraform はサブネット設定から情報を取得するため、a、b、c を指定する必要はありません。
