AWS - Scheduled shutdown and startup of the EC2 instances without AWS Instance Scheduler

I have found this simple method to schedule the start and stop of an AWS instance or a group of instances. This is simpler than using the CloudFormation Schuler template and this takes only 5 minutes to set up.

I got an error: parsing error identifier directly after number

const ec2 = new AWS.EC2({ region: event.instanceRegion });
ec2.stopInstances({ InstanceIds: [event.instanceId] }).promise()

I replaced instanceRegion = Availability Zone
instanceId = Instance ID

Does lamba charges for using stop start function?
