VPC中的Lambda无法访问DigitalOcean S3资源

我有部署在默认VPC中的Lambda,该VPC具有开放的端点到S3服务,Lambda具有IAM角色,可以广泛打开所有S3操作

iamRoleStatements:
  - Effect: "Allow"
    Action:
      - "rds:*"
      - "ec2:CreateNetworkInterface"
    Resource: "*"
  - Effect: Allow
    Action:
      - s3:*
    Resource: "*"

我正在NodeJS中通过以下方式访问S3 SDK:

const {
  DIGITAL_OCEAN_SPACES_ENDPOINT,
  DIGITAL_OCEAN_SPACES_ACCESS,
  DIGITAL_OCEAN_SPACES_REGION,
  DIGITAL_OCEAN_SPACES_SECRET,
  DIGITAL_OCEAN_SPACES_BUCKET_NAME,
} = process.env;

const spacesEndpoint = new Endpoint(DIGITAL_OCEAN_SPACES_ENDPOINT);
const S3Client = new S3({
  accessKeyId: DIGITAL_OCEAN_SPACES_ACCESS,
  endpoint: spacesEndpoint,
  region: DIGITAL_OCEAN_SPACES_REGION,
  secretAccessKey: DIGITAL_OCEAN_SPACES_SECRET,
});

Lambda超时-它无法连接到DigitalOcean S3存储桶。我还需要添加什么才能访问DO?
