we should be using get_json_env_var() https://github.com/profusion/kernelCI-dashboard/blob/main/backend/kernelCI/settings.py#L18C5-L18C21

just rebase your branch and you can use get_json_env_var

this is never to be used from within the code, but rather from some external env loader. Be it a source .env in the shell that calls the server, https://pypi.org/project/python-dotenv/ with a forced import before it runs...

anyway, never to be done/called-directly in the project code
