Unable to generate access token (using OAuth) from script.

[Rohan Saxena2]

I am using the below code:

var tokenRequest = new sn_auth.GlideOAuthClientRequest();
tokenRequest.setGrantType("authorization_code");

var oAuthClient = new sn_auth.GlideOAuthClient();
var tokenResponse = oAuthClient.requestTokenByRequest("<Oauth provider name>", tokenRequest);
gs.info("Error:" + tokenResponse.getErrorMessage());

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

And the output is : 

OAuthProblemException{error='Invalid request', description='null', uri='null', state='null', scope='null', redirectUri='null', responseStatus=0, parameters={}}
*** Script: Error:Invalid request
*** Script: AccessToken:null
*** Script: AccessTokenExpiresIn:0
*** Script: RefreshToken:null

I am able to generate the code/token from REST Message when I click "Get OAuth Token" UI action there but not from this script.

Also the code works while usinf SN to SN authorization, but I am trying with another 3rd party tool.

Does anyone has any ideas about what I might be missing, or a different approach for it.

Thanks

Hi Rohan,

Have you given proper application registry name in the method requestTokenByRequest

Yes it is correct else it throws an error stating "Couldn't find the OAuth Profile".
