Below script is working fine in ISE but if i run the same script in agent job iam getting blank output, can you please look into it and suggest me what changes i need to make

int] $Threshold = 20;
[Object[]] $computers = get-content -Path “”;
[string] $messagebody = “Server Name:” +$computer+”
Disk Name:” +$deviceid +”
Free Space Available:” +$freeSpaceGB +” GB

Recomendation-Either shrink the file or add more disk space to the server”;
[string] $smtpAddress = “”;
[string] $toAddress = “”;
[string] $fromAddress = “”;
foreach($computer in $computers){
$disks = Get-WmiObject -ComputerName $computer -Class Win32_LogicalDisk -Filter “DriveType = 3”;
$computer = $computer.toupper();
$deviceid = $disk.DeviceID;
foreach($disk in $disks){
$freeSpaceGB = [Math]::Round([float]$disk.FreeSpace/1073741824, 2);
if($freeSpaceGB -lt $Threshold){
[string] $username = “”;
[string] $password= “”;
[SecureString] $secpasswd = ConvertTo-SecureString $password -AsPlainText -Force;
[PSCredential] $mycreds = New-Object System.Management.Automation.PSCredential ($username, $secpasswd);
[string] $subject = “Warning Diskspace below the threshold”+ $computer +”for”+ $deviceid +”drive”;
Send-MailMessage -From $fromAddress -to $toAddress -Subject $subject -body $messagebody -smtpserver $smtpAddress -UseSsl -Port 25 -Credential $mycreds;
}
}

Any suggestions?

Thanks for sharing such a useful and detailed piece of information on scheduling PowerShell tasks with SQL Agent.
One little thing that is missing is the necessity of using -NoPorfile switch.
powershell.exe -NoProfile -File \\location\to\file.ps1
Otherwise, some of the cmdlets may fail. In particular, when calling Get-DbaBuildReference, we were getting the following error until we added the switch:
Error loading SQL build reference | Cannot bind argument to parameter ‘Path’ because it is null.
