retrieveAndGenerate Syntax Error: Unknown parameter generationConfiguration or retrievalConfiguration (Claude-v3, Amazon Bedrock)

I am trying to retrieve and generate response from knowledge base use claude-v3 model. To do so I followed the boto3 documentation and blog post on Amazon and created the following method:

def retrieveAndGenerate(input, kbId, modelArn=None):
    response = boto_runtime.retrieve_and_generate(
        input={
            'text': input
        },
        retrieveAndGenerateConfiguration={
            'knowledgeBaseConfiguration': {
                'generationConfiguration': {
                    'promptTemplate': {
                        'textPromptTemplate': promptTemplate
                    }
                },
                'knowledgeBaseId': kbId,
                'modelArn': modelArn,
                "retrievalConfiguration": {
                    'vectorSearchConfiguration': {
                        'numberOfResults': 5
                    }
                }
            },
            'type': 'KNOWLEDGE_BASE'
        }
    )
    
    return response

But it is giving me the following error:

ParamValidationError: Parameter validation failed: Unknown parameter in retrieveAndGenerateConfiguration.knowledgeBaseConfiguration: "generationConfiguration", must be one of: knowledgeBaseId, modelArn
Unknown parameter in retrieveAndGenerateConfiguration.knowledgeBaseConfiguration: "retrievalConfiguration", must be of one: knowledgeBaseId, modelArn

The same error is raised with even one of aforementioned fields.

I tried to put generationConfiguration and retrievalConfiguration out of knowledgeBaseConfiguration but those cases are also raising the same error.

It only works with minimum required fields like this:

def retrieveAndGenerate(input, kbId, modelArn=None):
    response = boto_runtime.retrieve_and_generate(
        input={
            'text': input
        },
        retrieveAndGenerateConfiguration={
            'knowledgeBaseConfiguration': {
                'knowledgeBaseId': kbId,
                'modelArn': modelArn
            },
            'type': 'KNOWLEDGE_BASE'
        }
    )
    
    return response

In both cases I am calling the method with the same inputs:

anthropicModelArns = ['arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-3-sonnet-20240229-v1:0']
response = retrieveAndGenerate(input='Felsefe nedir?', kbId='VPY6GXXXXX', modelArn=anthropicModelArns[0])

What is it I am doing wrong and how do I solve it? Appreciate your responses.
