unknown error: undefined method `+' for nil:NilClass
Help · 5 Dec 2021, 23:06 · 3

Does anybody know why I got this strange message when I try to Submit : "unknown error: undefined method `+' for nil:NilClass"?

First, check the way you quoted the positive sign `+' . Did you try to create a filename by using this `+' . May be you should change it to '+' instead `+'. These are the same signs but quoted differently.

Hello,

Please make sure your whole submission file is filled. If there are blank values rather fill them with 0.

Thank you, guys.

I had some empty fields, actually (wrong submission shape). I've fix it and it is working now.
