Uploading to SharepointOnline subfolder using Powershell - powershell

Question

it seems like I can upload a file to SPO's Site Collection URL but not the subfolder. For example, I can upload to "https://xyz.sharepoint.com/sites/Reporting", but not "https://xyz.sharepoint.com/sites/Reporting/Sales". Here's the working code's relevant bit:
$Username = "me#domain.com"
$Password = "Password"
$SiteCollectionUrl = "https://xyz.sharepoint.com/sites/Reporting"
$securePassword = ConvertTo-SecureString $password -AsPlainText -Force
$DocLibName = "Sales"
$Folder="C:\MySalesFolder"
Function Get-SPOCredentials([string]$UserName,[string]$Password)
{
$SecurePassword = $Password | ConvertTo-SecureString -AsPlainText -Force
return New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($UserName, $SecurePassword)
}
$Context = New-Object Microsoft.SharePoint.Client.ClientContext($SiteCollectionUrl)
$Context.Credentials = Get-SPOCredentials -UserName $UserName -Password $Password
#Retrieve list
$List = $Context.Web.Lists.GetByTitle($DocLibName)
$Context.Load($List)
$Context.ExecuteQuery()
#Upload file
Foreach ($File in (dir $Folder -File))
{
$FileStream = New-Object IO.FileStream($File.FullName,[System.IO.FileMode]::Open)
$FileCreationInfo = New-Object Microsoft.SharePoint.Client.FileCreationInformation
$FileCreationInfo.Overwrite = $true
$FileCreationInfo.ContentStream = $FileStream
$FileCreationInfo.URL = $File
$Upload = $List.RootFolder.Files.Add($FileCreationInfo)
$Context.Load($Upload)
$Context.ExecuteQuery()
I tried to hardcode "/Sales" subfolder but no luck. Anyone can point me in the right direction?

According to Trying to upload files to subfolder in Sharepoint Online via Powershell You will need to amend the FileCreationURL:
$FileCreationInfo.URL = $List.RootFolder.ServerRelativeUrl + "/" + $FolderName + "/" + $File.Name
I believe you just need to prepend $File.Name with the Folder path to your root directory.
Web.GetFolderByServerRelativeUrl Method:
Alternatively to attempting to Upload via List.RootFolder..., you can use the "GetFolderByServerRelativeUrl" method to get your Target Folder
$List = $Context.Web.Lists.GetByTitle($DocLibName)
$Context.Load($List.RootFolder)
$Context.ExecuteQuery()
$FolderName = "Sales"
$TargetFolder = $Context.Web.GetFolderByServerRelativeUrl($List.RootFolder.ServerRelativeUrl + "/" + $FolderName);
Then for upload you would use
$FileCreationInfo.URL = $File.Name
$UploadFile = $TargetFolder.Files.Add($FileCreationInfo)
$Context.Load($UploadFile)
$Context.ExecuteQuery()
