Validation Exception

[MaverickScientist]

Hi,
I am getting below exception while implementing agentic RAG, following your example from the file "rag-solutions/llamaindex-examples/2_llama_index_bedrock_kb.ipynb":
ValidationException: An error occurred (ValidationException) when calling the Retrieve operation: failed to create query: Field 'file_name.keyword' not found. Rewrite first

Below are the only changes I did in the original file to make it work for my use case:
knowledge_base_id = "my knowledge base id that exists in Bedrock"

llm = Bedrock(model = "anthropic.claude-3-sonnet-20240229-v1:0",region="ap-south-1")
embed_model = BedrockEmbedding(model = "cohere.embed-multilingual-v3",region="ap-south-1")

large_cap_fname = "Nippon India Large Cap Fund.pdf.md" #name of the actual file in the S3 bucket
large_cap_retriever = AmazonKnowledgeBasesRetriever(
knowledge_base_id=knowledge_base_id,
retrieval_config={
"vectorSearchConfiguration": {
"numberOfResults": top_k,
"overrideSearchType": search_mode,
"filter": {"equals": {"key": "file_name", "value": large_cap_fname}},
}
},
)
large_cap_engine = RetrieverQueryEngine(retriever=large_cap_retriever)

growth_fname = "Nippon India Growth Fund.pdf.md" #name of the actual file in the S3 bucket
growth_retriever = AmazonKnowledgeBasesRetriever(
knowledge_base_id=knowledge_base_id,
retrieval_config={
"vectorSearchConfiguration": {
"numberOfResults": top_k,
"overrideSearchType": search_mode,
"filter": {"equals": {"key": "file_name", "value": growth_fname}},
}
},
)
growth_engine = RetrieverQueryEngine(retriever=growth_retriever)

tools = [
QueryEngineTool(
query_engine=large_cap_engine,
metadata=ToolMetadata(
name="Large_Cap",
description="Facts about Nippon India Large Cap Fund June 2024",
),
)
,
QueryEngineTool(
query_engine=growth_engine,
metadata=ToolMetadata(
name="Growth",
description="Facts about Nippon India Growth Fund June 2024",
),
),
]

I get the exception when I generate the response using the below command:

response = await query_engine.aquery('Compare the portfolio share of ICICI Bank Ltd. between Large Cap & Growth Fund')

Please note that the knowledgebase exists and the .md files exist too in the knowledgebase as data sources.

Please help me fixing this issue.

Thanks,
Abhinav
