Express Query object undefined

I have an object postData which comes to the controller in form of query when I console log the object it has data:-

console.log("data:- ", req.query.postData);

console output:-

data:- {
         "property1":"value1",
         "property2":"value2",
         "property3":"value3",
         "property4":"value4"
       }

But when trying to restructure individual property:-

const {property1,property2,property3,property4} = req.query.postData;

console.log(property1);
console.log(property2);
console.log(property3);
console.log(property4);

console output:-

It is undefined in console log

>Solution :

postData is just a string. You need to convert it to an object with JSON.parse()

const {property1,property2,property3,property4} = JSON.parse(req.query.postData);

I don’t think passing JSON in the query string is really a good idea, though.

** instead, you could send it in the request body.

Or, for the query string use
?property1=value1&property2=value2&property3=value3&property4=value4
