AWS Lambda + REST calling assistance

I have a lambda function that works fine in calling a REST endpoint and returning exactly what i need. When i introduce a filter (for PDF's with tags in S3) as below, it shoots an error.

Need a fresh pair of eyes on it.

def retrieve(input_text, kbId):
print("Retrieving information for:", input_text, "from KB:", kb)
try:
response = bedrock_agent_runtime_client.retrieve(
knowledgeBaseId=kbId,
retrievalQuery={
'text': input_text
},
retrievalConfiguration={
"vectorSearchConfiguration": {
"numberOfResults": 5,
"filter": {
"andAll": [
{
"equals": {
"key": "Customer",
"value": "Apple"
}
}
]
}
}
}
)
return response
except Exception as e:
print(f"Error retrieving lambda data: {e}")
return {"error": str(e)}
