Oauth via Scheduled Job

[Ashby0003]

Hi I've created a Application Registry to connect to our AzureAD. 

If i go to the outbound rest message and click "Get oAuth Token" i receive the token and can run the API Call; however, i'm now attempting to refresh this token and run the call via a scheduled job. I have the below script which is giving me an error. 

var tokenRequest = new   sn_auth.GlideOAuthClientRequest();
var oAuthClient = new   sn_auth.GlideOAuthClient();
var tokenResponse = oAuthClient.requestTokenByRequest('{Name of Application Registry}',tokenRequest);

gs.log("Error:" + tokenResponse.getErrorMessage());
var token = tokenResponse.getToken();
gs.log("AccessToken:" + token.getAccessToken());
gs.log("AccessTokenExpiresIn:" + token.getExpiresIn());
gs.log("RefreshToken:" + token.getRefreshToken());

I ran this as a background script to more easily show the error.

 What am i missing? the Application Registry has a grant type listed... 

[ARG645]

Try adding a grant type parameter. 

var tokenRequest = new   sn_auth.GlideOAuthClientRequest();\


tokenRequest.setParameter('grant_type', 'password');//assuming your grant type in the application registry record is of type password


var oAuthClient = new   sn_auth.GlideOAuthClient();
var tokenResponse = oAuthClient.requestTokenByRequest('{Name of Application Registry}',tokenRequest);

gs.log("Error:" + tokenResponse.getErrorMessage());
var token = tokenResponse.getToken();
gs.log("AccessToken:" + token.getAccessToken());
gs.log("AccessTokenExpiresIn:" + token.getExpiresIn());
gs.log("RefreshToken:" + token.getRefreshToken());

Thanks, now i got a new error to investigate. haha

{error='invalid_request', description='AADSTS900144: The request body must contain the following parameter: 'code'.

I'm not even sure what it'd be expecting for this.
