Get-Item: Cannot find path ' ' because it does not exist. While running Powershell script.

Question

I am trying to run a PowerShell script to upload files into a SharePoint site in an Azure environment...the script works fine on my local machine, but every time I run it in Azure (remotely), I get errors. Here is what my simple script looks like...
if ( (Get-PSSnapin -Name Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue) -eq $null )
Write-Host "Loading Sharepoint Module "
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")
Add-PSSnapin -Name Microsoft.SharePoint.PowerShell
if ( (Get-PSSnapin -Name Microsoft.SharePoint.PowerShell) -eq $null )
Write-Host "Failed to load sharepoint snap-in. Could not proceed further, Aborting ..."
Exit
#Script settings
$webUrl = "http://sampleWebUrl"
$docLibraryName = "My Documents"
$docLibraryUrlName = "My%20Documents"
$localFolderPath = get-childitem "C:\Upload\Test Upload\My Documents\" -recurse
$contentType = "ContenttType1"
#Open web and library
$web = Get-SPWeb $webUrl
write-host "Web:" $web
$docLibrary = $web.Lists[$docLibraryName]
write-host "docLibrary:" $docLibrary
$files = ([System.IO.DirectoryInfo] (Get-Item $localFolderPath)).GetFiles()
write-host "files:" $files
If ($contentType = "ContenttType1")
#Open file
$fileStream = ([System.IO.FileInfo] (Get-Item $file.FullName)).OpenRead()
# Gather the file name
$FileName = $File.Name
#remove file extension
$NewName = [IO.Path]::GetFileNameWithoutExtension($FileName)
#split the file name by the "-" character
$FileNameArray = $NewName.split("_")
$check = $FileNameArray.Length
#Add file
$folder = $web.getfolder($docLibrary.rootFolder.URL)
write-host "Copying file " $file.Name " to " $folder.ServerRelativeUrl "..."
$spFile = $folder.Files.Add($folder.Url + "/" + $file.Name, [System.IO.Stream]$fileStream, $true)
$spItem = $spFile.Item
write-host "Success"
write-host "SP File:" $spFile
write-host "SP Item" $spItem
#populate columns
$spItem["Column1"] = $FileNameArray[0]
$spItem["Column2"] = $FileNameArray[1]
$spItem.Update()
$fileStream.Close();
Again, I can run this on my local machine and it works just fine, but when I attempt to run it on the Azure environment I get this error...
Get-Item : Cannot find path 'C:\powershellscripts\12653_B7045.PDF' because it does not exist.
At C:\PowerShellScripts\Upload-FilesIntoSharePointTester.ps1:32 char:42
+     $files = ([System.IO.DirectoryInfo] (Get-Item $localFolderPath)).GetFiles()
+                                          ~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (C:\powershellscripts\12653_B7045.PDF:String) [Get-Item], ItemNotFoundException
    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetItemCommand
What strikes me first is the fact that the file its looking for is in the "C:\Upload\Test Upload\My Documents\" directory, but the error keeps saying "C:\powershellscripts\" which is where my script resides and not the files I want to
upload into SharePoint. When I step through the code, all the variables are holding the correct values. The $localFolderPath shows the name of files that I am attempting to upload, so it recognizes them. But once I step through this particular line of code,
the error occurs...
$files = ([System.IO.DirectoryInfo] (Get-Item $localFolderPath)).GetFiles()
Is this an error caused because I am remoting into the Azure environment? Has anyone dealt with this issue before? I would really appreciate the help. Thanks
Update: quick thing I noticed is that these two lines of code are returning null values. Again, is this handled differently in Azure or remotely? I ask cause this is the way I know how to do this, locally.
$docLibrary = $web.Lists[$docLibraryName]
$files = ([System.IO.DirectoryInfo] (Get-Item $localFolderPath)).GetFiles()

"...square brackets are wildcard characters in Windows PowerShell..."
When you use cd without a parameter it uses the -Path parameter. In this case you'll have to escape the square brackets so they are not considered wildcards. Each of the commands in the first example does the exact same thing.
cd 'Learn PowerShell `[Do Whatever`]'
cd -Path 'Learn PowerShell `[Do Whatever`]'
cd (or Set-Location) also has a literal path parameter (-LiteralPath) that does not require using an escape character (`) before each of the brackets. Hope this helps.
cd -LiteralPath 'Learn PowerShell [Do Whatever]'
