REST API accessToken datasetId field

[jcaffarel]

Hi,

I'm trying to set up a Power BI dashboard using NodeJS and ejs with the REST API. (https://stackoverflow.com/questions/47194412/node-js-app-integration-with-power-bi-rest-api)

I've managed to successfully login from my code and get the access token from 

https://login.microsoftonline.com/common/oauth2/token.

To my understanding, after that, I need to get another access token from 

https://api.powerbi.com/v1.0/myorg/groups/{groupId}/reports/{reportId}, by means of setting an Authorization header like "Authorization" "Bearer {receivedToken}" and sending a GET request to that URL. The issue is that, after that request, I receive a response with fields such as:

@odata.context, id, webUrl, etc. but the only "new" field that I receive is a "datasetId". However, I can't seem to find the description of that field, but I assume is the accessToken that needs to be passed in the "config" object to the powerbi.embed(...., config) function. Am I right?

The problem is that on the webpage, a message of "This content is not available" is shown, and checking the console errors, I can see a 403 error for the resource: https://wabi-south-east-asia-redirect.analysis.windows.net/metadata/cluster

Is there something I'm missing? Any help would be greatly appreciated.
