通过 django celery 发送电子邮件时出现 Gmail 身份验证错误

Question

TL;DR：尝试使用 Django 应用程序中的 Celery/RabbitMQ 任务发送电子邮件时，我从 Gmail 收到 SMTPAuthenticationError，尽管传入的凭据是正确的。在没有 Celery 的情况下正常发送电子邮件时不会发生这种情况。

嗨，

我正在尝试在我的 Django 应用程序中使用 Celery/RabbitMQ 向用户异步发送电子邮件。我有以下代码发送电子邮件：

from grad.celery import app
from django.core.mail import EmailMultiAlternatives
from django.template.loader import get_template
from django.template import Context
from grad import gradbase
from time import sleep
from grad import settings

@app.task
def send_transaction_email(student_data, student_email):
    html_email = get_template('grad/student_email.html')
    context = Context({
        'name': student_data['name'],
        'university': student_data['university'],
        'data': student_data,
        'shorturl':  gradbase.encode_graduation_data(student_data)
    })
    msg = EmailMultiAlternatives('Subject Here',
                             'Message Here',
                             'myrealemailaddress@gmail.com',
                             [student_email])
    msg.attach_alternative(html_email.render(context), "text/html")
    msg.send()

当我正常调用方法时：

tasks.send_transaction_email(entry, stud_email)

电子邮件发送正常，但如果我像这样将调用委托给 Celery 任务：

tasks.send_transaction_email.delay(entry, stud_email)

我得到以下跟踪：

Traceback (most recent call last):

基本上 Gmail 无法识别凭据，尽管当我在导致崩溃的那一行之前的两行上逐字打印它们时，它们是正确的。

有人可以帮助我吗？

尝试在此处设置一个应用密码 https://security.google.com/settings/security/apppasswords 并将其用作 STMP 设置中的密码。
