Lambda PowerShell Functions Do Not Log Debug Messages to CloudWatch Messages

[ashovlin]

Describe the bug

We already have internal case and ticket V1078993289 for this, but creating this so others can track a fix publicly.

Expected Behavior

"Write-Debug" should print to CloudWatch messages when adding -Debug parameter or using $DebugPreference to get the message displayed on console.

Current Behavior

Messages aren't logged.

Possible Solution

This probably is happening because "Write-Debug" isn't included in these events https://github.com/aws/aws-lambda-dotnet/blob/master/Libraries/src/Amazon.Lambda.PowerShellHost/PowerShellFunctionHost.cs#L294

The change has been released in AWSLambdaPSCore 4.0.2.0.

Kindly note the following to enable debugging:

• Refer $DebugPreference. In PowerShell code, you:
  • Either need to set $DebugPreference = "Continue" at the beginning of script; OR
  • Include -Debug parameter while executing Write-Debug (e.g. Write-Debug "Testing Lambda PowerShell Write-Debug" -Debug)
• Also set environment variable AWS_LAMBDA_HANDLER_LOG_LEVEL with value DEBUG (refer blog post Introducing the .NET 6 runtime for AWS Lambda). This will enable Debug logs at Lambda level.
