I am trying to render a simple Jinja template. No matter what the template is, or what variables are passed to it, I get an error when trying to render. Why am I getting this error and how do I fix it?
frontend = Blueprint('frontend', __name__, template_folder='templates')
@frontend.route('/')
def index():
stuff = dict()
stuff['page_title'] = 'Something'
stuff['center_piece'] = 'Random'
return render_template('base.html', stuff=stuff)
Basic template, without variables, still causes error.
<html>
<head>
<title>Something</title>
</head>
<body>Something else</body>
</html>
