I'm not able to deploy Django to AWS Lambda using Zappa connecting to RDS, it is showing me below error:

NameError: name '_mysql' is not defined:

Here are my AWS CloudWatch logs:

And below is my config:


    'default': {

        'ENGINE': 'django.db.backends.mysql',

        'NAME': 'raags-instance', # DB Instance created in AWS RDS

        'USER': 'xyz',

        'PASSWORD': 'passwordpassword',

        'HOST': '*********',

        'PORT': 3306,



Any solution for this?

Here the problem is because the ".mysql" file is missing in the MySQL dB directory.

You can add the below lines in code and try to deploy again, it should work fine.

import pymysql
