AEM JCR - Get response as JSON

We are adding some metadata under a specific location in JCR:

POST /some/jcr/location/_jcr_content/json HTTP/1.1
Accept: application/json
Authorization: Basic YWRtaW46YWRtaW4=
Cache-Control: no-cache
Host: localhost:4502
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
Content-Type: multipart/form-data; boundary=--------------------------554953211468377919703514
Cookie: cq-authoring-mode=TOUCH
Content-Length: 383
----------------------------554953211468377919703514
Content-Disposition: form-data; name="./value"

{ "test": "test" }
----------------------------554953211468377919703514
Content-Disposition: form-data; name=":cq_csrf_token"

ey***our csrf token***-c5Oa0
----------------------------554953211468377919703514--

But when we fetch this same resource, the response type is test/html`:

GET /some/jcr/location/jcr:content/json/value HTTP/1.1
Accept: application/json
Cache-Control: no-cache
Host: localhost:4502
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
Cookie: cq-authoring-mode=TOUCH

HTTP/1.1 200 OK
Date: Fri, 26 Feb 2021 13:49:38 GMT
X-Content-Type-Options: nosniff
Content-Type: text/plain;charset=utf-8 
Content-Length: 18
{ "test": "test" }

What configuration do we need to add in JCR, or what do we need to edit in our request to make sure that JCR returns content type application/json.

UPDATE: As Sharath Madappa replied, you can request the data in JSON format by suffixing the location with the .json extension. However, that results in the following format:

{
    "value": "{ \"test\": \"test\" }"
}

While I expect it to be:

{
    "test": "test"
}

You can also specify the depth you want to go for besides having JSON format response.

E.g Depth of 1(just the node) in JSON format:

curl -u <user>:<pass> -v <URL>/some/jcr/location/jcr:content/json/value.1.json

All child nodes under a certain path in JSON format:

curl -u <user>:<pass> -v <URL>/some/jcr/location.-1.json

Posting JSON content and then retrieving it as Content-Type: application/json can be done by file upload instead of adding properties.

Here is a javascript example:

const data = { test: "test" };
const jsonData = new Blob([JSON.stringify(data)], { type: 'application/json' });
const formData = new FormData();
formData.append(`myFile.json`, jsonData, `myFile.json`);

return fetch(path, {
  method: 'POST',
  body: formData
});

This example does not take in account Authn/Authz.

To fetch you data as application/json, you just issue a GET call to the location of the JSON file:

http://localhost:4502/path/to/the/folder/jcr:content/files/myFile.json

use GET /some/jcr/location/jcr:content/json/value.json while making the request. Sling is able to render/return the resource in multiple formats based on the extension in the request. By default, if no extension is provided it goes with HTML. The path tells which resource, the extension, and selectors tell how and what renders the resource.
