Analytics api1.4 JWT Service Grant

Hi All,

          We are starting to use adobe analytics api 1.4 and followed the steps that are documented in gihub. Even though our integration is successful using client credentials grant type,  our security team asked us to use JWT grant . We are having  issues with claims in JWT token , we are able to get the access token from the oauth endpoint but unfortunately we are getting below response from the resource server. In the JWT token , we are passing  Org_id as subject, client id as issuer and private key. And the application is registered by our IMS admin. Can anyone please help us resolving this , we tried reaching client care as well.
