Greetings. I’m using MongoDB to store information regarding a project I am doing in javascript. There are multiple values I am trying to increment or decrease periodically and it has been working so far, but for this one I always get a “Cannot increment with non-numeric argument” error, which doesn’t make sense to me because my argument is clearly a number, if I check it with javascript’s “typeof” function, it tells me it’s a number. I convert it from string to number via parseInt() and also it works in other scenarios, just not here for some reason.
Can someone help me find out why am I getting the error? My code:
const amountAdded = parseInt(args[0], 10)
await client.db.userdata.updateOne({
id: message.author.id,
}, {
$inc: {
inventory: {
common: {
quantity: amountAdded
}
}
},
});
Error:
“MongoError: Cannot increment with non-numeric argument: {inventory: { common: { quantity: 1 } }}”
Here is an instance where it does work:
client.db.userdata.updateOne({
id: targetUser.id,
}, {
$inc: {
balance: payAmount,
},
});
