部署失败：使用AWS CodeDeploy从Bitbucket部署

Question

我能够将bitbucket与aws链接，尽管bitbucket的部署会在下面返回错误。

Deployment Failed
The deployment failed because no IAM role with the IAM role name (arn:aws:iam::******:role/m30role) specified in this request was found. Make sure you are using the correct name of a service role that exists in your account. (Error code: IAM_ROLE_MISSING) Learn more

对此有何想法？或者我应该检查aws的哪个部分

有关使用AWS CodeDeploy设置从Bitbucket部署的优秀教程的任何建议。

    }
  ]
}

部署配置：CodeDeployDefault.OneAtATime

从bitbucket构建（部署到AWS）已上传到s3存储桶，我能够查看所有部署历史记录，但之后所有构建都失败了。
