Description
Describe the bug
Required parameter StorageConfiguration for CfnKnowledgeBase appears to have been added to CDK with 2.140.0 (closing #29966 with PR #30037). The python bindings, however, appear to have not been updated, as the parameter is not recognized in the CfnKnowledgeBase L1 construct for Python, defined as below:
def __init__(
self,
scope: _constructs_77d1e7e8.Construct,
id: builtins.str,
*,
knowledge_base_configuration: typing.Union[_IResolvable_da3f097b, typing.Union["CfnKnowledgeBase.KnowledgeBaseConfigurationProperty", typing.Dict[builtins.str, typing.Any]]],
name: builtins.str,
role_arn: builtins.str,
description: typing.Optional[builtins.str] = None,
tags: typing.Optional[typing.Mapping[builtins.str, builtins.str]] = None,
) -> None:Expected Behavior
The constructor should include the parameter and should create the knowledge base.
Current Behavior
The constructor does not include the parameter. Trying cdk deploy without the parameter results in the following error:
╰─ cdk deploy

Reproduction Steps
The stack is as follows:
from aws_cdk import (RemovalPolicy,
Stack,
aws_bedrock as bedrock,aws_s3 as s3,
aws_s3_deployment as s3_deployment)
from constructs import Construct
class HotelAssistantStack(Stack):
def __init__(self, scope: Construct, construct_id: str, **kwargs) -> None:
super().__init__(scope, construct_id, **kwargs)
# Bedrock Agents-related resources
# S3 bucket that will be used for our storage needs
bucket = s3.Bucket(scope=self,
id='AgentKBDocsBucket',
versioned=False,
encryption=s3.BucketEncryption.S3_MANAGED,
event_bridge_enabled=True,
removal_policy=RemovalPolicy.DESTROY,
enforce_ssl=True,
auto_delete_objects=True)
s3_deployment.BucketDeployment(scope=self,
id='AgentKBDocsDeployment',
sources=[s3_deployment.Source.asset('docs',
exclude=['*.pptx', '*.docx'])],
destination_bucket=bucket)
model_arn = bedrock.FoundationModel.from_foundation_model_id(
scope=self,
_id='EmbeddingsModel',
foundation_model_id=bedrock.FoundationModelIdentifier('cohere.embed-english-v3')).model_arn
knowledge_base = bedrock.CfnKnowledgeBase(scope=self,
id='AgentKB',
name='HotelDataKB',
role_arn='arn:aws:iam::123456789012:role/service-role/'
'AmazonBedrockExecutionRoleForKnowledgeBase_vz9pm',
knowledge_base_configuration={'type': 'VECTOR',
'vectorKnowledgeBaseConfiguration': {
'embeddingModelArn': model_arn}})
# Create the data source; we could also define the chunking strategy, but let's leave its default values
bedrock.CfnDataSource(scope=self,
id='AgentKBDataSource',
name='HotelDataS3Source',
knowledge_base_id=knowledge_base.attr_knowledge_base_id,
data_source_configuration={'s3Configuration': {'bucketArn': bucket.bucket_arn},
'type': 'S3'})Possible Solution
