I am creating an application making use of Express, but I’m facing that mistake :

var str = this.parameters[i].toString();

When trying to add values to inputs from localhost:3000/admin/games. I searched here in the forum, but most of the topics I found had in their logs information of where the error was, in this case it does not specifically inform and I’m not able to track even if I found something similar in Why do I get Cannot read Property ' toString ' of Undefined, but again, I’m not making use of toString and it wouldn’t be nice to edit that in the package Mysql 2 which I assume is making use of this function, or it would still be likely that the error is found in my application code ?
Obs : project Futiba on Github and when I call input ' save ' it sends me the following message
Could you put a snippet (piece) of code for us to evaluate, please? Probably,
this.parameters[i]does not exist (is Undefined) because the index i is out of the tamano range of this Parameters– Luis Fedrizze
This Feature is related to these two files : https://github.com/Sphinxs/Futiba/blob/master/admin.js#L41 and https://github.com/Sphinxs/Futiba/blob/master/views/admin/games.ejs#L95 ( Ps, I set anchor to go straight to the part of the code that I think the error is in )

I checked the codes, the error could be in game.game_id or in Guess.id. One of these 2 items is returning Undefined. Try debugging these variables.
