NodeJS: retrieving an array which is wrapped in a string

I'm currently trying to save a mail object () I'm getting back from an API into our Mongo database. This is all fine for all values being passed accept the field 'attachments'. The attachments are supposed to be an array of objects, but this is wrapped in a string. My question now is: how do I get the array out of that string?

Example of the req.body which I'm getting from the POST request:

{ timestamp: '1538728432', token: '0a1336769443d5a593d0ef7c1c817d29ef64ba422fc3cc45f1', signature: 'c44c67660f0ad97bbb5ece92c733302d4511d4607b5787ae6aa8f2203b0e2e3e',

JSON.parse should do the trick

const response = {
  timestamp: '1538728432',
  token: '0a1336769443d5a593d0ef7c1c817d29ef64ba422fc3cc45f1',
  Subject: '2 attachments',
  attachments: '[{"url": "https://se.api.mailgun.net/v3/domains/karaton.uk/messages/eyJwIjpmYWxzZSwiayI6IjEyNzQ1ZmViLTM4OTItNDdkZC04MTJiLWJlYzU4ZjNjYTI4MCIsInMiOiI1NDE1ODQ0ZjIyIiwiYyI6InRhbmtiIn0=/attachments/0", "content-type": "application/pdf", "name": "WOORDZOEKER maken _ Online _ Met oplossing2 copy.pdf", "size": 53398}, {"url": "https://se.api.mailgun.net/v3/domains/karaton.uk/messages/eyJwIjpmYWxzZSwiayI6IjEyNzQ1ZmViLTM4OTItNDdkZC04MTJiLWJlYzU4ZjNjYTI4MCIsInMiOiI1NDE1ODQ0ZjIyIiwiYyI6InRhbmtiIn0=/attachments/1", "content-type": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "name": "Geschatte uren.xlsx", "size": 44210}]'
}

const attachments = JSON.parse(response.attachments);
console.log(attachments[0]);
console.log(attachments[1]);

Use the built-in JSON.parse() function, it'll return an array of objects as it should. It's opposed to JSON.stringify(), which does the opposite. So, basically, JSON.parse(req.body.attachments) should do the trick.
