Sending JSON via Postman causes an error in my Node.js service - arrays

Question

I created schema in node.js. It worked before I included arrays.
This is my schema code:
const Item = new item_Schema({
info:{
title:{type:String, required:true},
bad_point:{type:Number, 'default':0},
Tag:{type:String, required:true}
},
review:{
Review_text:{type:Array, required:true},
Phone_list:{type:Array, required:true},
LatLng_list:{type:Array, required:true}
}
});
Item.statics.create = function(info, review){
const list = new this({
info:{
title,
bad_point,
Tag
},
review:{
Review_text,
Phone_list,
LatLng_list
}
});
return list.save();
};
This is my register code:
exports.register = (req, res) => {
const { info, review } = req.body
const create = (list) => {
return Item.create(info, review)
}
const respond = () => {
res.json({
message: 'place route registered successfully'
})
}
const onError = (error) => {
res.status(409).json({
message: error.message
})
}
RouteReviewItem.findOneBytitle(title)
.then(create)
.then(respond)
.catch(onError)
}
And this is the Postman JSON raw code:
{
"info":"{
"title":"test title",
"badPoint":"0"
"Tag":"tag1"
}",
"review":"{
"Review_text":["1번리뷰", "2번리뷰", "3번리뷰"],
"Phone_list":"["010-0000-0000", "010-1111-1111", "010-2222-2222"],
"LatLng_list":["111.1111,111.1111", "222.222,222.222","333.3333,333.3333"]
}"
}
This is the error I get in Postman:
SyntaxError: Unexpected token in JSON at position 17

Is this a problem with postman? Or the node.js side?
I looked at the node.js book I was studying, but could not find any relevant information.

Answer 1

The code is fine, you have an issue with JSON you used for testing. For further testing and debugging, I suggest that you verify that the requests you send you the endpoint are correct by using a service like JSONLint (or any offlne tool that does the same). For the request you posted in the question, this service complains:
Error: Parse error on line 2:
{ "info": "{ "title": "test t
----------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'
Next time, before sending a request, make sure it is correct syntactically. That way you'll know that there is a problem with your code, and won't spend time debugging a non-existent issue.
