我试图使用Glue数据库连接来连接到Redshift。我按照本教程https://docs.aws.amazon.com/glue/latest/dg/setup-vpc-for-glue-access.html设置了用于粘合的vpc以访问Redshift。此外，通过成功使用Workbench访问Redshift，我确保我的用户名和密码正确。然后，确保我使用的IAM角色是具有AmazonS3FullAccess，AWSGlueServiceRole，AmazonRedshiftFullAccess，AWSGlueConsoleFullAccess策略的Glue服务规则。最后，我添加了decrypt策略来访问与Redshift相关的KMS密钥。
但是，我仍然收到以下权限错误。不确定哪一步出错了？
