Nested multipart data is not supported

I am attaching image as suggested in docs, but get this error, what is wrong, how to do it differently?

let bytes: [UInt8] = Array(buffer: body)
var bytesBuffer = ByteBufferAllocator().buffer(capacity: bytes.count)
bytesBuffer.writeBytes(bytes)
let file = File.init(data: bytesBuffer, filename: "\(ti.eventId)_0.cover.jpg")

//let file = File(data: img, filename: "\(ti.eventId)_0.cover.jpg")
let mgm = MailgunMessage(from: emailFrom, to: [u.invoiceDetails!.email], replyTo: nil, cc: nil, bcc: nil, subject: e.welcomeEmailSubject ?? "Welcome", text: text, html: nil, attachments: [file], inline: nil)
print("Welcome message will be sent \(u.name)")
fflush(stdout)
return request.mailgun(.myApp1).send(mgm).map { (cr) -> (String) in
    print("Welcome message sent: \(u.name)")
    fflush(stdout)
    return "Welcome message sent \(u.name)"
}

I would like to send a PDF attachment and am also getting the error mentioned in the title. I first make an API call to a 3rd party service that returns a Data object, then I follow the docs and convert it to ByteArray and use it to create a File. I'm able to create a PDF document and show it inside a PDFView an iOS app, which means the data is not corrupt. Is there an error in the docs, or am I missing something?

Had the same issue. If I understood the Mailgun API docs correctly, the attachment option expects a single file, not an array of files:

attachment: File attachment. You can post multiple attachment values.

So to attach multiple files you need to provide several attachment options, not a single option with an array of files.

I changed code in MailgunMessage from:

public let attachment: [File]?

to

public let attachment: File?

Then I was able to send and receive an email with an attached file.

@madsodgaard would the new multipart-kit address this original issue?

It will do once the nested data PR is merged
