# PowerShell script file to be executed as a AWS Lambda function.
#
# When executing in Lambda the following variables will be predefined.
# $LambdaInput - A PSObject that contains the Lambda function input data.
# $LambdaContext - An Amazon.Lambda.Core.ILambdaContext object that contains information about the currently running Lambda environment.
#
# The last item in the PowerShell pipeline will be returned as the result of the Lambda function.
#
# To include PowerShell modules with your Lambda function, like the AWS.Tools.S3 module, add a "#Requires" statement
# indicating the module and version. If using an AWS.Tools.* module the AWS.Tools.Common module is also required.
#
# The following link contains documentation describing the structure of the S3 event object.
# https://docs.aws.amazon.com/AmazonS3/latest/dev/notification-content-structure.html
 
#Requires -Modules @{ModuleName='AWS.Tools.Common';ModuleVersion='4.0.5.0'}
#Requires -Modules @{ModuleName='AWS.Tools.S3';ModuleVersion='4.0.5.0'}
 
# Uncomment to send the input event to CloudWatch Logs
# Write-Host (ConvertTo-Json -InputObject $LambdaInput -Compress -Depth 5)
