How to extract a parameter of JSON object that is full with escape characters - '\'

I have a serverless project running on Node JS that gets a respons to it with the following escape character - "\". Here is my object that I get as a response to me - 

"{\"desc\":\"India next talent\",\"name\":\"אחלה ברווז\",\"uid\":\"-LnQwxh_QoYl4Qj_9M4B\"}"

So basiclly, as you can see, this is a JSON object with some wierd escape characters. The full object is called

reqBody.context.custom.miniContest

So what I need is the 'uid' parameters of the miniContest, but when trying to call it - 

reqBody.context.custom.miniContest.uid

I get undefined. So my question is how can I extract the value of 'uid' successfully?

It seems you're doing JSON.stringify() twice. You can avoid it if you've the access on the server side codebase.

Say, If you have this,

const config = {a: 1, b: 2}
console.log(JSON.stringify(JSON.stringify(config)))

then it will produce below response with extra \,

"{\"a\": 1, \"b\": 2}"

To extract the value of 'uid' successfully, You can use JSON.parse() to make it object before accessing it, Let's do it this way-

let json = "{\"desc\":\"India next talent\",\"name\":\"אחלה ברווז\",\"uid\":\"-LnQwxh_QoYl4Qj_9M4B\"}";

let result = JSON.parse(json);
console.log(result.uid);
