Attached local PDF files

[walmins]

Hello,
I try to send local PDF files but isn't work,

          with open(src_pdf, 'rb') as f:
            pdf_file = f.read()
          attachments = [
            ("my_pdf_file.pdf", pdf_file, 'application/pdf')
            ]
          pm = PMMail(
            to=user_mail, 
            bcc=pmBCC,
            sender=pmSender,
            template_id=email_template_id,
            template_model=template_model,
            api_key=pmApiKey,
            attachments=attachments,
            tag=pmTag)
          pm.send()

do you know what is wrong?
Thanks

What happens when you do a normal read on the file, not a read-bytes?

with open(src_pdf, 'r') as f:
