How can I modify my code to negate this error?

Question

Here is my function, on file streamMonitor.ps1

function streamMonitor {
    [cmdletbinding()]
    param(
        [string]$directoryPath,
        [string]$scriptToRestartPath
    )

    while ($true) {
        Write-Host "Monitoring directory: $directoryPath"
        Write-Host "Script to restart: $scriptToRestartPath"
        # Get the current time
        $currentTime = Get-Date

        # Get the latest creation time of any file in the directory
        $latestCreationTime = Get-ChildItem -Path $directoryPath -Recurse |
            Where-Object { !$_.PSIsContainer } |
            Sort-Object CreationTime -Descending |
            Select-Object -First 1 |
            ForEach-Object { $_.CreationTime }

        # Ensure $latestCreationTime is not $null
        if ($null -eq $latestCreationTime) {
            Write-Host "No files found in the directory."
            return
        }

        # Check if the latest write time is within the last 30 seconds
        $timeDifference = New-TimeSpan -Start $latestCreationTime -End $currentTime
        if ($timeDifference.TotalSeconds -gt 30) {
            # No changes in the last 30 seconds, restart the specified script
            Write-Host "No changes detected within the last 30 seconds. Restarting script..."
            Start-Process -FilePath "cmd.exe" -ArgumentList "/c `"$scriptToRestartPath`"" -NoNewWindow
        }
        else {
            Write-Host "Changes detected within the last 30 seconds. No action taken."
        }

        Start-Sleep -Seconds 30
        continue
    }
}

Here is the script at which I invoking parallel instances of my function on a separate PowerShell file:

$streamMonitor = @(
    @{
        directoryPath       = 'C:\pathto\stream2'
        scriptToRestartPath = 'C:\pathto\stream2.bat'
    }
    @{
        directoryPath       = 'C:\pathto\stream3'
        scriptToRestartPath = 'C:\pathto\stream3.bat'
    }
    @{
        directoryPath       = 'C:\pathto\stream1'
        scriptToRestartPath = 'C:\pathto\stream1.bat'
    }
)
    
$streamMonitor | ForEach-Object {
    Start-Job {
        . C:\pathto\streamMonitor.ps1
        streamMonitor @using:_
    }
} | Receive-Job -Wait -AutoRemoveJob

This is the error I am getting:
