(aws-lambda-destinations): update docs to warn users that Fifo queues aren't supported as destinations #13793
Description
During creation of a Lambda defined in a Python stack, a status code 400 InvalidParameterValueException is thrown. It fails to create the SQS on_failure DestinationConfig and the stack creation fails with a rollback.
Reproduction Steps
Deploying the following stack triggers the failure:
from aws_cdk import (
core,
aws_lambda as lambda_,
aws_lambda_destinations as lambda_dest,
aws_sqs as sqs,
)
from aws_cdk.aws_lambda_python import PythonFunction
class StackHello(core.Stack):
def __init__(self, scope: core.Construct, construct_id: str,
**kwargs) -> None:
super().__init__(scope, construct_id, **kwargs)
self._create_hello_lambda()
def _create_hello_lambda(self) -> None:
q = sqs.Queue(
scope=self,
id='hello-fail.fifo',
queue_name='hello-fail.fifo',
encryption=sqs.QueueEncryption.KMS_MANAGED,
fifo=True,
content_based_deduplication=True,
visibility_timeout=core.Duration.seconds(90)
)
fn = PythonFunction(
scope=self,
id='hello_function',
handler='main',
entry='hello',
index='hello.py',
runtime=lambda_.Runtime.PYTHON_3_7,
on_failure=lambda_dest.SqsDestination(q)
)
q.grant_send_messages(fn)What did you expect to happen?
Trying to deploy a Lambda function through the CDK that sends any message that failed to process to a dead letter queue.
What actually happened?
The deploy fails with the exception below:
8:32:00 AM | CREATE_FAILED | AWS::Lambda::EventInvokeConfig | hello_function/EventInvokeConfig
The provided destination config DestinationConfig(onSuccess=OnSuccess(destination=), onFailure=OnFailure(destination=arn:aws:sqs:us-east-1:<redacted>:hello-fail.fifo)) is invalid. (Service: AWSLambdaInternal; Status Code: 400; Error Code: InvalidParameterValueEx
