Htpp submit and get in cocos creator – Cocos Creator

hey guys dev,
I’ve an issue with my api, I needed to combine my api with an http script and I made request for get and ship for submit
However the issue is on the stage of the submit which makes an error once I could make the process of registration of a participant, I obtain an error once I introduce a phone quantity in my ship I resolve an error

const url_server="https://check.fapfap.jambo-games.com"

let hash



var HTTP = {

            var str = "?";
            for(var okay in knowledge){
                if(str != "?"){

const HTTP = require('../../Http');

cc.Class({
    extends: cc.Part,

    properties: {
        phone_number: cc.EditBox
    },

    // LIFE-CYCLE CALLBACKS:

    createPlayer () {
        console.log('telephone', this.phone_number)
       const knowledge = {
            country_code: "CM",
           phone_number: "+237" + "695715681" ,
        }
        var onCreate = perform(res){
            console.log('resp', res)
            cc.director.loadScene("checkNumber");
        }
        console.log('knowledge', knowledge)

     HTTP.ship('/auth/register-or-login', knowledge, onCreate)
    
    },

error en console

I need to know if there’s a chance that we can’t register a participant together with his quantity? Or solely with username and password?

Thanks prematurely to your solutions
