Cookiecutter - Django: Anymail[SES] boto3 region error - django

Question

I am trying to deploy to AWS(EC2) a Cookiecutter Django project.
The AWS user with this credentials has ful S3, SES and SNS policies.
The EC2 server has also a role with full SES/S3 policies.
In production file in envs I have the keys set up like this.
DJANGO_AWS_ACCESS_KEY_ID=xxxxxxxxx
DJANGO_AWS_SECRET_ACCESS_KEY=xxxxxxxxxx
DJANGO_AWS_STORAGE_BUCKET_NAME=xxxxxxxxxx
In settings I have
AWS_S3_REGION_NAME = env("DJANGO_AWS_S3_REGION_NAME", default=None)
AWS_ACCESS_KEY_ID = env("DJANGO_AWS_ACCESS_KEY_ID")
AWS_SECRET_ACCESS_KEY = env("DJANGO_AWS_SECRET_ACCESS_KEY")
AWS_STORAGE_BUCKET_NAME = env("DJANGO_AWS_STORAGE_BUCKET_NAME")
EMAIL_BACKEND = "anymail.backends.amazon_ses.EmailBackend"
ANYMAIL = {}
All nice and fine until the project tries to send an email using SES and it crashes with the error bellow .
Until now I have tried:
adding DJANGO_AWS_S3_REGION_NAME to the production file in envs - no result
adding the region in aws config using aws cli - no result
overriding the settings in ANYMAIL ={} with credetials and region - no result
making a blank project, just adding the aws credentials and not changing anything else - no result
creating manually on another project a boto3.session.client with the same credentials and sending a mail - it works
This is the error. The second part with 'NoneType' object has no attribute 'send_raw_email' repeats a lot after this.

I'll appreciate any input. I'm out of ideas.
Thanks!

As you've probably figured out, the problem is boto3 doesn't know what AWS region you're trying to operate in:
botocore.exceptions.NoRegionError: You must specify a region.
The region name comes from boto3 configuration. From Anymail's SES docs:
you must make sure boto3 is configured with AWS credentials having the necessary IAM permissions. There are several ways to do this; see Credentials in the Boto docs for options. Usually, an IAM role for EC2 instances, standard Boto environment variables, or a shared AWS credentials file will be appropriate. For more complex cases, use Anymail’s AMAZON_SES_CLIENT_PARAMS setting to customize the Boto session.
It seems like you might be try to mix some of the "several ways" to provide boto3 credentials, which could be causing confusion.
Note that your AWS_* Django settings don't come into play. boto3 doesn't know about Django settings. Anymail's SES settings docs describe which Django settings Anymail will pass along to boto3. (And AWS_S3_REGION_NAME wouldn't be relevant anyway, because S3 is not the same service as SES. I'm guessing those AWS_* Django settings may be for some other app, maybe django-storages.)
If you want to provide AWS credentials specifically for Anymail in settings.py, you can do that with Anymail's AMAZON_SES_CLIENT_PARAMS setting. E.g.:
# (Be sure to add DJANGO_AWS_REGION_NAME to your env to use this example)
ANYMAIL = {
"AMAZON_SES_CLIENT_PARAMS": {
"aws_access_key_id": env("DJANGO_AWS_ACCESS_KEY_ID"),
"aws_secret_access_key": env("DJANGO_AWS_SECRET_ACCESS_KEY"),
"region_name": env("DJANGO_AWS_REGION_NAME"),
},
}
