はじめに

ハンズオンを実施中にエラーが出てきたのでメモ
今回使用したハンズオンはCDKのワークショップです。
初心者のため誤りがあればご指摘ください

本課題と異なる点としては個人AWSアカウントに対して設定を行っており、IAMユーザーではなくIAM Identity Centerで払い出したSSOユーザーを使用しています。
事前にaws configure ssoにてCLI側で設定済み

今回のエラー内容

Unable to resolve AWS account to use. It must be either configured when you define your CDK Stack, or through the environment

＜直訳＞
使用するAWSアカウントを解決できません。
CDK Stack を定義する際に設定するか、または環境設定によって設定する必要があります。

確認

使用するAWSアカウントを解決できないということはSSOのセッションが切れた可能性あるかなと思い、確認

aws s3 ls --profile <プロファイル名>

Error when retrieving token from sso: Token has expired and refresh failed

予想通りだったため、再ログイン実施

$ aws sso login --profile <プロファイル名>

If the browser does not open or you wish to use a different device to authorize this request, open the following URL:
