ERROR: Cannot validate argument on parameter 'Message'.

[powertronglobal]

Followed setup instructions, when I run it , it starts runs for about 1 min and throws this error. Any ideas?

Write-EventLog : Cannot validate argument on parameter 'Message'. The argument is null, empty, or an element of the argument collection contains a null value. Supply a collection that does not contain any null values and then try t command again. At C:\aws\3-ebs-snapshot.ps1:39 char:101

• ... 1337 -Message $global:log_message

  - CategoryInfo          : InvalidData: (:) [Write-EventLog], ParameterBindingValidationException
  - FullyQualifiedErrorId : ParameterArgumentValidationError,Microsoft.PowerShell.Commands.WriteEventLogCommand

Hmm, that's on the log function that runs at the end of the script. Does your snapshot get created?

[powertronglobal]

wow that was fast. Snapshot doesn’t get created.

I was setting this other backup script up yesterday: https://github.com/noahlh/aws-automated-backup-powershell ran it today and it stopped working , which lead me to your solution looking for another. Maybe its a problem with aws. I’ll give it a shot again in the morning. Your solution looked really clean and was hoping it would work.

thanks for the reply.

@powertronglobal What was the outcome? I'm getting the same thing today.

C:>powershell.exe -ExecutionPolicy Bypass -file "C:\aws\3-ebs-snapshot.ps1"

When I run it by hand I get an access error. Hmm... C:\Program Files\Amazon\AWSCLI>aws ec2 describe-volumes

C:\Program Files\Amazon\AWSCLI>

This error seems to correspond...and I don't see any EID1377 entries.

The machine-default permission settings do not grant Local access permission to the COM Server application C:\Windows\Explorer.EXE with APPID Unavailable to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

I just realized that the error above says Event ID 1337 and 1377, but neither actually show up.

Snapshot" -EntryType $type -EventID 1337 -Message $global:log_message esults written to the Event Log (check under Applications, Event ID 1377).
