Send Mail with attachment via Powershell Graph API - powershell

Question

I'm currently trying to send a mail using an automated Powershell script using the GraphAPI from Microsoft.
Here the full story : I need to check every 15 min the mail received on an Office 365 mailbox, get a specific file attachment (filter by is name), download the file, and re-send it with a new mail.
Everything working but I canno't send the new mail with the attachment ( Works without the attachment).
Here my code :
$date = (get-date).ToUniversalTime().AddMinutes(-15).ToString("yyyy-MM-ddTHH:mm:ssZ")
$Uri = "https://graph.microsoft.com/v1.0/me/messages"
$UriSend = "https://graph.microsoft.com/v1.0/me/sendMail"
$filter = "?`$select=Id,ReceivedDateTime&`$filter=HasAttachments eq true and ReceivedDateTime ge " + $date
$url = $Uri + $filter
$Result = (Invoke-RestMethod -Method Get -Headers $requestheader -Uri $url)
if($Result.value){
## Loop through each results
foreach ($message in $Result.value)
{
# get attachments and save to file system
$query = $Uri + "/" + $message.Id + "/attachments"
$attachments = (Invoke-RestMethod -Method Get -Headers $requestheader -Uri $query)
# in case of multiple attachments in email
foreach ($attachment in $attachments.value)
{
$patternPDF = "FAX AR document\.pdf$"
if($attachment.Name -match $patternPDF)
{
$name = $message.ReceivedDateTime -replace "T","-"
$name = $name -replace "Z",""
$name = $name -replace ":","-"
$path = "c:\Temp\" + $name + ".pdf"
# Creation of the PDF file
$Content = [System.Convert]::FromBase64String($attachment.ContentBytes)
Set-Content -Path $path -Value $Content -Encoding Byte
$file = Get-Content $path -Encoding Byte -ReadCount 0
#Send File by Mail
$body =
#"
{
"message" : {
"subject": "AR Fax",
"body" : {
"contentType": "Text",
"content": "Accusé Fax"
},
"toRecipients": [
{
"emailAddress" : {
"address" : "mail#domain.com"
}
}
],
"attachments":[
{
"##odata.type":"#microsoft.graph.fileAttachment",
"name":"Fax_AR.pdf",
"contentType":"application/pdf",
"contentBytes":"$file"
}
]
},
"saveToSentItems": "true"
}
"#
# Invokes the request
Invoke-RestMethod -Headers $requestheader -Uri $uriSend -Method Post -Body $body
I'm not very good in powershell (or in code generally) so please be indulgent^^
EDIT : I've find another way to do what i want (I print the file now)
