bug: Events.Rule is not filtering by EventPattern #11335
Description
Is there an existing issue for this?
- I have searched the existing issues
Current Behavior
Given there are multiple AWS::Events::Rules triggering the same target (lambda) only last rule is applied, without filtering down to rules satisfying EventPattern property.
Expected Behavior
All rules are applied that are filtered down with EventPattern.
How are you starting LocalStack?
With a docker-compose file
Steps To Reproduce
Given localstack is up with docker compose up
# docker-compose.yml
services:
localstack:
image: localstack/localstack:latest
environment:
- PROVIDER_OVERRIDE_EVENTS=v2
- DEBUG=1
ports:
- "127.0.0.1:4566:4566" # LocalStack Gateway
- "127.0.0.1:4510-4559:4510-4559" # external services port range
volumes:
- "${LOCALSTACK_VOLUME_DIR:-./tmp/localstack}:/var/lib/localstack"
- "/var/run/docker.sock:/var/run/docker.sock"
And stack
# cloudformation.yaml`

is deployed using cli command
aws cloudformation create-stack --stack-name minimal-example --capabilities CAPABILITY_NAMED_IAM --template-body file://cloudformation.yaml --endpoint-url http://localhost:4566 --region us-east-1
on dispatching eventbridge event
aws events put-events --endpoint-url http://localhost:4566 --region us-east-1 --entries file://event_v2.json
#event_v2.json
[
{
"EventBusName": "default",
"Source": "com.mycompany.myapp",
"Detail": "{ \"payload\": { \"id\": \"987654321\", \"name\": \"John Doe\" } }",
"Resources": [
"resource1",
"resource2"
],
"DetailType": "myDetailType"
}
]
triggers EventRuleWithoutPayload instead of EventRuleWithPayload.
Validation is preformed by tailing a log group
aws logs tail /aws/lambda/AwsLambdaMinimalExample --endpoint-url http://localhost:4566 --region us-east-1 --follow
More so, if EventRuleWithAnotherType is uncommented and the same event is dispatched, EventRuleWithAnotherType is triggered, although should not as detail-type should filter this rule out.
