我突然开始无处不在的出现了这个错误，而且几周没有问题，而且我似乎无法找出导致它的原因。 这是完整的错误
TypeError: Cannot read property 'substr' of undefined

它似乎指向功能
function getFullNumber(cash){
var newcash = -1;
if(!isNaN(Number(cash))){
newcash = Number(cash);
} else {
var suffix = cash.substr(cash.length-1);
suffix = suffix.toLocaleUpperCase();
switch(suffix){
case "K":
newcash = Number(cash.substr(0,cash.length-1))*1000;
break;
case "M":
newcash = Number(cash.substr(0,cash.length-1))*1000000;
break;
case "B":
newcash = Number(cash.substr(0,cash.length-1))*1000000000;
break;
case "T":
newcash = Number(cash.substr(0,cash.length-1))*1000000000000;
break;
case "Q":
newcash = Number(cash.substr(0,cash.length-1))*1000000000000000;
break;
}
}
return newcash;
}
和
function init(cash){
try {
cash = getFullNumber(cash);
if(cash <= 0) return;
var userData = JSON.parse(fs.readFileSync(client.config.dataFolder + "/users/" + currentUser + ".json", "utf8"));
var arr = getMaxItems(userData, cash);
if(arr){
if(arr.length==0){
client.users.get(currentUser).send("You Need More Cash!");
} else {
var text = ahk(arr);
var file = client.config.dataFolder + "/ahks/" + getFileName();
fs.writeFileSync(file, text);
client.users.get(currentUser).send({
files: [{
//attachment: 'C:/Bots/Cafe/Cafe Team Bot ver 2.4.0/test.ahk',

});
}
}
//if(str.length>0)
//client.users.get(currentUser).send(str + "\n`++++++++++++++++++++++++++++++`");
} catch(err){
console.log(err);

不确定为什么会突然出现这种情况，但是任何帮助都是很棒的！

似乎，init函数将不正确的参数传递给getFullNumber。 只需放一些警卫来检查现金是否为typeof字符串。也许像
else if(typeof cash === 'string') {
var suffix = cash.substr(cash.length-1);
...
}
// Let the newcash default value return.
进行编辑以包含最大的示例。
function getFullNumber(cash){
var newcash = -1;
if(!isNaN(Number(cash))){
newcash = Number(cash);
}
else if(typeof cash === 'string') {
var suffix = cash.substr(cash.length-1);
suffix = suffix.toLocaleUpperCase();
switch(suffix){
case "K":
newcash = Number(cash.substr(0,cash.length-1))*1000;
break;
case "M":
newcash = Number(cash.substr(0,cash.length-1))*1000000;
break;
case "B":
newcash = Number(cash.substr(0,cash.length-1))*1000000000;
break;
case "T":
newcash = Number(cash.substr(0,cash.length-1))*1000000000000;
