v2.29.0

Summary

Standardized Retrieval of API Gateway Authorizer Context

This release standardizes how to retrieve the API Gateway authorizer context in both v1 and v2 of the Lambda handler. Previously, there were inconsistencies in how customers retrieved authorization context between V1 and V2 payloads.

from aws_lambda_powertools.event_handler import APIGatewayRestResolver
from aws_lambda_powertools import Logger

app = APIGatewayRestResolver()
logger = Logger(level="INFO")


@app.get("/")
def initialize():
    context: dict = app.current_event.request_context.authorizer.get_context()
    logger.info(context.get("tenantId"))

def lambda_handler(event, context):
    return app.resolve(event, context)

We also fixed an issue with dependency injection when using decorators in the Lambda handler function. Previously, dependencies were not properly injected when decorators were present, leading to runtime errors.

v2.28.0

Summary

This release adds support for Data Validation and automatic OpenAPI generation in Event Handler.

Even better, it works with your existing resolver (API Gateway REST/HTTP, ALB, Lambda Function URL, VPC Lattice)!

Did you read that correctly? Yes, you did! Look at this:

Data validation

Docs: Data validation

By adding enable_validation=True to your resolver constructor, you’ll change the way the resolver works. We will:

1. inspect your route handlers to gather input and output types (including Pydantic models and dataclasses)
2. validate and coerce the input data for you automatically before invoking your route handlers
3. validate and coerce the output data for you automatically after invoking your route handlers
4. enable a cool feature (see the next section!)

This moves data validation responsibilities to Event Handler resolvers, reducing a ton of boilerplate code. You can now focus on just writing your business logic, and leave the validation to us!

from typing import List, Optional

import requests
from pydantic import BaseModel, Field

from aws_lambda_powertools import Logger, Tracer
from aws_lambda_powertools.event_handler import APIGatewayRestResolver
from aws_lambda_powertools.logging import correlation_paths
from aws_lambda_powertools.utilities.typing import LambdaContext

tracer = Tracer()
logger = Logger()
app = APIGatewayRestResolver(enable_validation=True)  


class Todo(BaseModel):  
    userId: int
    id_: Optional[int] = Field(alias="id", default=None)
    title: str
    completed: bool


@app.post("/todos")
def create_todo(todo: Todo) -> str:  
    response = requests.post("https://jsonplaceholder.typicode.com/todos", json=todo.dict(by_alias=True))
    response.raise_for_status()

    return response.json()["id"]  


@app.get("/todos")
@tracer.capture_method
def get_todos() -> List[Todo]:
    todo = requests.get("https://jsonplaceholder.typicode.com/todos")
    todo.raise_for_status()

    return todo.json()  


@logger.inject_lambda_context(correlation_id_path=correlation_paths.API_GATEWAY_HTTP)
@tracer.capture_lambda_handler
def lambda_handler(event: dict, context: LambdaContext) -> dict:
    return app.resolve(event, context)

OpenAPI generation

Docs: OpenAPI generation

When you enable data validation, we automatically inspect your API in a way that makes it possible to generate OpenAPI specifications automatically!

You can export the OpenAPI spec for customization, manipulation, merging micro-functions, etc., in two ways:

• Pydantic model using app.get_openapi_schema()
• JSON Schema using app.get_openapi_json_schema()

Here’s one way to print the schema if you were to run your Python Lambda handler locally:

import requests

from aws_lambda_powertools.event_handler import APIGatewayRestResolver
from aws_lambda_powertools.event_handler.openapi.models import Contact, Server
from aws_lambda_powertools.utilities.typing import LambdaContext

app = APIGatewayRestResolver(enable_validation=True)


@app.get("/todos/<todo_id>")
def get_todo_title(todo_id: int) -> str:
    todo = requests.get(f"https://jsonplaceholder.typicode.com/todos/{todo_id}")
    todo.raise_for_status()

    return todo.json()["title"]


def lambda_handler(event: dict, context: LambdaContext) -> dict:
    return app.resolve(event, context)


if __name__ == "__main__":
    print(
        app.get_openapi_json_schema(
            title="TODO's API",
            version="1.21.3",
            summary="API to manage TODOs",
            description="This API implements all the CRUD operations for the TODO app",
            tags=["todos"],
            servers=[Server(url="https://stg.example.org/orders", description="Staging server")],
            contact=Contact(name="John Smith", email="[email protected]"),
        ),
    )

Can you see where this is going? Keep reading :)

Swagger UI

Docs: Swagger UI

Last but not least... you can now enable an embedded Swagger UI to visualize and interact with your newly auto-documented API!

from typing import List, Optional

import requests
from pydantic import BaseModel, Field

from aws_lambda_powertools import Logger, Tracer
from aws_lambda_powertools.event_handler import APIGatewayRestResolver
from aws_lambda_powertools.logging import correlation_paths
from aws_lambda_powertools.utilities.typing import LambdaContext

app = APIGatewayRestResolver(enable_validation=True)  
app.enable_swagger()  # by default, path="/swagger"

@app.get("/todos")
@tracer.capture_method
def get_todos() -> List[Todo]:
    todo = requests.get("https://jsonplaceholder.typicode.com/todos")
    todo.raise_for_status()

    return todo.json()
    
def lambda_handler(event: dict, context: LambdaContext) -> dict:
    return app.resolve(event, context)

The Swagger UI appears by default at the /swagger path, but you can customize this to serve the documentation from another path, and specify the source for Swagger UI assets.

We can’t wait for you try this new features!

v2.27.1

Summary

This patch release addresses the following issues:

• Static typing. Mypy/Pyright no longer complains about Logger.addFilter/removeFilter
• Documentation. Add note in Event Handler that Amazon API Gateway doesn't handle catch all (*/*) binary types when CORS is configured
• Logger Correlation ID. You can now use Powertools custom JMESPath Functions to extract correlation ID from data serialized in JSON string, Base64, and GZIP -- @logger.inject_lambda_context("powertools_json(body).my_field")

🌟 Big thanks to @rafrafek and @martinber for their critical eye in spotting some of these issues

v2.27.0

Summary

This minor release adds support for two new environments variables to configure the log level in Logger.

You can now configure the log level of for Logger using two new environment variables: AWS_LAMBDA_LOG_LEVEL and POWERTOOLS_LOG_LEVEL.

The new environment variables will work along the existing LOG_LEVEL variable that is now considered legacy and will be removed in the future.

Setting the log level now follows this order:

1. AWS_LAMBDA_LOG_LEVEL environment variable
2. Setting the log level in code using the level constructor option, or by calling the logger.setLevel() method
3. POWERTOOLS_LOG_LEVEL environment variable

v2.26.0

v2.26.0 Release notes

Summary

This release adds richer exception details to the logger utility, support for VPC Lattice Payload V2, smarter model inference in the parser utility, expanded ARM64 Lambda Layer support on additional regions, and fixes some bugs!

⭐ Huge thanks to our new contributors: @Tom01098, @stevrobu, and @pgrzesik!

Richer exception details

Docs: logger

The logger utility now logs exceptions in a structured format to simplify debugging. Previously, exception tracebacks appeared as a single string containing the raw stack trace frames. Developers had to parse each frame manually to extract file names, line numbers, function names, etc.

With the new serialize_stacktrace flag, the logger prints stack traces as structured JSON. This clearly surfaces exception details like filenames, lines, functions, and statements per frame. The structured output eliminates the need to parse traceback strings, improving observability and accelerating root cause analysis.

Amazon VPC Lattice Payload V2

Docs: event handler, parser

Amazon VPC Lattice is a fully managed application networking service that you use to connect, secure, and monitor the services for your application across multiple accounts and virtual private clouds (VPC). You can register your Lambda functions as targets with a VPC Lattice target group, and configure a listener rule to forward requests to the target group for your Lambda function.

With this seamless integration, you can now leverage the performance benefits of Amazon VPC Lattice Payload V2 directly in your event handlers. The latest release enables handling Lattice events using the familiar event handler API you already know, including critical features like CORS support and response serialization.

Model inference in the parser utility

Docs: parser

The event_parser decorator previously required you to duplicate the type when using type hints. Now, the event_parser decorator can infer the event type directly from your handler signature. This avoids having to redeclare the type in the event_parser decorator.
