我正在使用当前的Celery 4.0.0，redis-server stable和rabbitmq运行Python3 Django 1.10.3。在Windows和Linux ubuntu上都会发生此错误。谷歌搜索此错误并未产生任何结论性结果。
这是错误堆栈：

导致此错误的代码是：
email = rodSendEmail.delay(zadeva, clan, sporocilo, request, msgid)
和任务链接：
@shared_task
def rodSendEmail(zadeva, clan, body, request, msgid):
try:
now = str(datetime.datetime.utcnow().replace(tzinfo=utc))
plaintext = get_template('rod/email/clani_msg.txt')
htmly = get_template('rod/email/clani_msg.html')
d = Context(
{
'message': body,
'rodIme': request.user.info.rod.rodIme,
'rodNaslov': request.user.info.rod.rodNaslov,
'pattern': 'erod',
}
)
strFrom = str(request.user.get_full_name()) + ' via eRod<erod@ksoft.si>'
subject, from_email, to, replyto = zadeva, strFrom, [clan.clanEmail], [
request.user.info.rod.rodEmail]
text_content = plaintext.render(d)
html_content = htmly.render(d)
msg = EmailMultiAlternatives(subject, text_content, from_email, to, reply_to=replyto,

msg.attach_alternative(html_content, "text/html")
msg.mixed_subtype = 'related'
msg.send()
except smtplib.SMTPException:

finally:
return True
