Django S3 image upload error "boto.exception.S3ResponseError: S3ResponseError: 400 Bad Request"

Question

I'm trying to upload an image with Django Rest Framework and AWS S3.

settings.py:

AWS_ACCESS_KEY_ID = ... 
AWS_SECRET_ACCESS_KEY = ... 
AWS_STORAGE_BUCKET_NAME = ... 
AWS_S3_CUSTOM_DOMAIN = '%s.s3.amazonaws.com' % AWS_STORAGE_BUCKET_NAME AWS_S3_OBJECT_PARAMETERS = {
        'CacheControl': 'max-age=86400', } 
AWS_LOCATION = 'static'

STATICFILES_DIRS = [
        os.path.join(BASE_DIR, 'backend/static'), ] STATIC_URL = 'https://%s/%s/' % (AWS_S3_CUSTOM_DOMAIN, AWS_LOCATION) STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'  DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage' 

AWS_DEFAULT_ACL = None

models.py:

class Beat(models.Model):
    ...
    image = models.ImageField(upload_to='static/', default = 'static/None/No-img.gif', null = True)

S3 bucket policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Allow All",
            "Effect": "Allow",
            "Principal": "*",
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:PutObjectAcl"
            ],
            "Resource": "arn:aws:s3:::my_bucket/*"
        }
    ]
}

However, when I upload an image, it gives error:

boto.exception.S3ResponseError: S3ResponseError: 400 Bad Request

I can't figure out what the problem is.

python manage.py collectstatic works well.

How can I fix this error?

Thanks.

settings.py needed the lines below:

AWS_REGION = 'ap-northeast-2'
AWS_S3_HOST = 's3.%s.amazonaws.com' % AWS_REGION
