刷新网页后访问令牌无效 AWS Cognito (Amazon Cognito)

Question

AWS Cognito flutter web on refresh web page access token 无效
我正在使用 Flutter 构建 Web 应用程序

 CognitoClientException {
            statusCode: 400, 
            code: NotAuthorizedException, 
            name: NotAuthorizedException, 
            message: Invalid Access Token
   }

注意：刷新前和刷新后token相同
