Deploy: Spooky environment variable

I have a strange problem when deploying.
For deploying I set the environment variables via file and an export:

production.conf
DJANGO_CONFIGURATION=“Prod”
DJANGO_SECRET_KEY=“abc”
DJANGO_DATABASE_URL=“mysql://testuser:testpwd@localhost/testdb”

export $(cat production.conf | xargs)

After python3 manage.py makemigrations I get the following error messages:

’ . Did you mean: ‘Prod’?module ‘test.settings’ has no attribute 'Prod

If I enter the value of the environment variable DJANGO_CONFIGURATION manually, everything is ok.

DJANGO_CONFIGURATION=“Prod”
export DJANGO_CONFIGURATION

python3 manage.py makemigrations
No changes detected

The value of the environment variable DJANGO_DATABASE_URL does not cause any problem, only DJANGO_CONFIGURATION.

I was thinking of an encoding problem, but that’s probably out of the question. Also because env always shows the same values ​​for DJANGO_CONFIGURATION. But the same value is obviously not the same for Django after all.

Does anyone have an explanation for this?

What happens when you unquote the value "Prod"Prod?
