Release notes

Sourced from aws-lambda-powertools's releases.

v3.30.0

Summary

This release adds a custom serializer option to the BedrockAgentResolver, plus documentation improvements and bug fixes across the Event Handler.

A huge thanks to @​kimnamu, @​Avinm and @​hirenkumar-n-dholariya for their contributions!

Custom serializer on BedrockAgentResolver

Docs

You can now pass your own serializer to BedrockAgentResolver, the same way the other resolvers already allow. This lets you control exactly how responses are serialized to JSON, for example to handle custom types or tune the output format.

import json
from decimal import Decimal
from aws_lambda_powertools.event_handler import BedrockAgentResolver
from aws_lambda_powertools.utilities.typing import LambdaContext
def custom_serializer(obj: dict) -> str:
return json.dumps(obj, default=str)
app = BedrockAgentResolver(serializer=custom_serializer)
@​app.get("/price", description="Returns the current price")
def get_price() -> dict:
return {"price": Decimal("9.99")}
def lambda_handler(event: dict, context: LambdaContext):
return app.resolve(event, context)
