Jsonify(lineup) = error ?

[Duell10111]

I get an HTTP 500 error with jsonify(lineup) using json.dumps resolves my problem ;)

jsonify no longer supports encoding arrays, for (bogus in my view) security reasons.

I changed the jsonify line to
try:
return Response(json.dumps(lineup), mimetype='application/json');
except Exception as e:
print('An error occured: ' + repr(e))
