Issue connecting Django to database - sql-server

Question

I'm currently using python 3.6 and django 2.1.11. I have a database I'm trying to connect to to make migrations.
Currently my settings looks like:
'Project': {
'ENGINE': "sql_server.pyodbc",
'HOST': os.environ.get("DJANGO_DB_SERVER"),
'USER': os.environ.get("DJANGO_DB_UID"),
'PASSWORD': os.environ.get("DJANGO_DB_PWD"),
'NAME': "Project",
'CONN_MAX_AGE' : 600,
'OPTIONS': {
'driver': 'ODBC Driver 17 for SQL Server',
}
},
I have the settings set in a PowerShell script that I run to set up the env variables. When I try and make migrations I get the following error:
django.db.utils.InterfaceError: ('28000', "[28000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Login failed for user 'mssql_appuser'. (18456) (SQLDriverConnect); [28000] [Microsoft][ODBC Driver 17 for SQL Server]Invalid connection string attribute (0); [28000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Login failed for user 'mssql_appuser'. (18456); [28000] [Microsoft][ODBC Driver 17 for SQL Server]Invalid connection string attribute (0)")
I went into pyodc base file and added a print statement to see what my connection string looked like:
DRIVER=ODBC Driver 17 for SQL Server;SERVER=db_name;UID=test;PWD=test;DATABASE=Project;MARS_Connection=yes
Not sure whats wrong here. If I attempt to add {} around the driver in the ps1 file the connection comes up like this:
DRIVER={{ODBC Driver 17 for SQL Server}}};SERVERNAME=db_name;UID=test;PWD=test;DATABASE=Project
which seems incorrect
Any advice on how to fix this would be appreciated
