 If you are sending Lifecycle termination events from ASG directly to SQS, instead of through EventBridge, then you will also need to create an IAM service role to give Amazon EC2 Auto Scaling access to your SQS queue. Please follow [these linked instructions to create the IAM service role: link.](https://docs.aws.amazon.com/autoscaling/ec2/userguide/configuring-lifecycle-hook-notifications.html#sqs-notifications)
