AWS Lake Formation：grant_permissions：Resource.Table 中的未知参数："TableWildcard"

Question

正在尝试通过 Lambda 函数授予 Lake 权限。 (Python 3.8) 据我所知，我根据文档获得了我的代码。然而，却遇到了一连串关于参数不正确的无意义错误。难道我只需要一个配镜师？还是有些细微差别，或者今天亚马逊的风吹向哪个方向？

import boto3
import json
from botocore.exceptions import ClientError

def main(event,context):

    client = boto3.client('lakeformation')

    response = client.grant_permissions(
        Principal={
            'DataLakePrincipalIdentifier': 'arn:aws:iam::123456789012:role/myRole'
        },
        Resource={
            'Table': {
                'DatabaseName': 'myDatabase',
                'TableWildcard': {}
            },
        },
        Permissions=['ALL'],
        PermissionsWithGrantOption=['ALL']
    )

我调查了一下这个问题。错误是因为在 lambda 上，TableResoures 的定义是（注意 lambda 上缺少的 TableWildcard）：

    "TableResource":{
      "type":"structure",
      "required":[
        "DatabaseName",
        "Name"
      ],
      "members":{
        "DatabaseName":{
          "shape":"NameString",
          "documentation":"<p>The name of the database for the table. Unique to a Data Catalog. A database is a set of associated table definitions organized into a logical group. You can Grant and Revoke database privileges to a principal. </p>"
        },
        "Name":{
          "shape":"NameString",
          "documentation":"<p>The name of the table.</p>"
        }
      },
      "documentation":"<p>A structure for the table object. A table is a metadata definition that represents your data. You can Grant and Revoke table privileges to a principal. </p>"
    }

相比之下，latest version on github 有：

    "TableResource":{
      "type":"structure",
      "required":["DatabaseName"],
      "members":{
        "CatalogId":{
          "shape":"CatalogIdString",
          "documentation":"<p>The identifier for the Data Catalog. By default, it is the account ID of the caller.</p>"
        },
        "DatabaseName":{
          "shape":"NameString",
          "documentation":"<p>The name of the database for the table. Unique to a Data Catalog. A database is a set of associated table definitions organized into a logical group. You can Grant and Revoke database privileges to a principal. </p>"
        },
        "Name":{
          "shape":"NameString",
          "documentation":"<p>The name of the table.</p>"
        },
        "TableWildcard":{
          "shape":"TableWildcard",
          "documentation":"<p>A wildcard object representing every table under a database.</p> <p>At least one of <code>TableResource$Name</code> or <code>TableResource$TableWildcard</code> is required.</p>"
        }
      }

在我看来这是一个错误。

AWS Lake Formation : grant_permissions : Unknown parameter in Resource.Table: "TableWildcard"
