linkedin API cannot create campaign

We have got rw_ads permissions for an app. Through that app We have taken access_token with all given permissions.

As mentioned in the documentation, we have rw_ads permission, but If we try to create/update campaign we are getting the below error.

{ "serviceErrorCode": 100, "message": "Not enough permissions to access: POST /adCampaignsV2/sdafnk", "status": 403 }

var request = require("request");

var options = { method: 'POST',
  url: 'https://api.linkedin.com/v2/adCampaignsV2/sdafnk',
  headers: 
   { 'Authorization': 'Bearer XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
     'Content-Type': 'application/json' },
  body: 
   { patch: 
      { '$set': 
         { runSchedule: { end: 1548405000000, start: 1547713800000 },
           status: 'ACTIVE' } } },
  json: true };

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(body);
});
