You are overriding the 'page' argument given to the function, which is what you
want, with the value of the 'page' query string parameter, which is a
completely different thing, but because it isn't passed, falls back to using
'index.html'.
Comment out the line:
page = request.args.get('page', 'index.html')
Do not use that.
