Powershell upload a pdf file using boundary MIME to RightFax Web Service - powershell

Question

I am trying to upload a pdf file into Right fax via the RightFax Web Api. I can do this via PostMan and I am able to send the attachment afterwards. When I try do upload via PowerShell an I send my attachment I only get the Object Name in the actual fax ex. System.Net.Http.StreamContent. Here is my borrowed powershell code:
Add-Type -AssemblyName System.Net.Http
$AuthURL = "http://" + $RESTAPIServer + "/RightFax/API"
$BaseURL = "http://" + $RESTAPIServer + "/RightFax/API/SendJobs"
$AttachURL = "http://" + $RESTAPIServer + "/RightFax/API/Attachments"
$Base = [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($RESTAPIUser+":"+$RESTAPIPassword))
$vCenterSessionURL = $BaseAuthURL
$Header = #{"Authorization" = "Basic "+[System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($RESTAPIUser+":"+$RESTAPIPassword))}
$TARGET_FOLDER_PATH = "\\SomeFolderPath\"
$TokenUri = "http://" + $RESTAPIServer + "/RightFax/API/Login?rememberMe={rememberMe}"
$Token = Invoke-RestMethod -Method GET -Headers $Header -Uri $TokenUri
Get-ChildItem $TARGET_FOLDER_PATH -Filter *.pdf |
Foreach-Object {
$TARGET_FILE_NAME = $_.Name
$LDA_TARGET_FILE_NAME = $TARGET_FOLDER_PATH + $TARGET_FILE_NAME
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Authorization", "Basic $Base")
$fileName = $TARGET_FILE_NAME
$uri = $AttachURL
$filePath = $LDA_TARGET_FILE_NAME
$FileStream = [System.IO.FileStream]::new($filePath, [System.IO.FileMode]::Open)
$fileContent = [System.Net.Http.StreamContent]::new($FileStream)
$boundary = [System.Guid]::NewGuid().ToString()
$LF = "`r`n"
$bodyLines = (
"--$boundary",
"Content-Disposition: attachment; name=`"$fileName`"; filename=`"$filePath`"",
"Content-Type: application/octet-stream",
"Content-Transfer-Encoding: base64$LF",
$fileContent,
"--$boundary--$LF"
) -join $LF
$Attach = Invoke-RestMethod -Uri $uri -Headers $headers -Method Post -ContentType "multipart/form-data; boundary=`"$boundary`"" -Body $bodyLines #-InFile $filePath
write-host $Attach
$FileStream.Dispose()
$fileContent.Dispose()
}

I figured it out. I needed to encode the file. For those of you who are here to actually get help and not here to play police for other users posts but neglect to add any actual positive helpful comments.... Here is the code for RightFax add attachments to a fax.
$AttachURL = "http://" + $RESTAPIServer + "/RightFax/API/Attachments"
$Base = [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($RESTAPIUser+":"+$RESTAPIPassword))
$vCenterSessionURL = $BaseAuthURL
$Header = #{"Authorization" = "Basic "+[System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($RESTAPIUser+":"+$RESTAPIPassword))}
$TARGET_FOLDER_PATH = "\\SomeFolderPath\"
$TokenUri = "http://" + $RESTAPIServer + "/RightFax/API/Login?rememberMe={rememberMe}"
$Token = Invoke-RestMethod -Method GET -Headers $Header -Uri $TokenUri
Get-ChildItem $TARGET_FOLDER_PATH -Filter *.pdf |
Foreach-Object {
$TARGET_FILE_NAME = $_.Name
$LDA_TARGET_FILE_NAME = $TARGET_FOLDER_PATH + $TARGET_FILE_NAME
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Authorization", "Basic $Base")
$fileName = $TARGET_FILE_NAME
$uri = $AttachURL
$filePath = $LDA_TARGET_FILE_NAME
$fileRead = [IO.File]::ReadAllBytes($filePath)
$enc = [System.Text.Encoding]::GetEncoding("iso-8859-1")
$fileEnc = $enc.GetString($fileRead)
$boundary = [System.Guid]::NewGuid().ToString()
$LF = "`r`n"
$bodyLines = (
"--$boundary",
"Content-Disposition: form-data; name=`"$fileName`"; filename=`"$ResultFilePath`"", # filename= is optional
"Content-Type: application/pdf$LF",
$fileEnc,
"--$boundary--$LF"
) -join $
$Attach = Invoke-RestMethod -Uri $uri -Headers $headers -Method Post -ContentType "multipart/form-data; boundary=`"$boundary`"" -TimeoutSec 20 -Body $bodyLines
Write-host $Attach
}

I'm setting up a different fax service (SRFax) that needs the attachments in base64.
$file = [IO.File]::ReadAllBytes("C:\Users\Path\To\File.pdf")
$filebase64 = [System.Convert]::ToBase64String($file)
