Error: Access not granted or expired. Service_.getAccess

[Nibesh Khadka]

I get this error,

 Error: Access not granted or expired.

Service_.getAccessToken

@ Service.gs:518

I tried clearing and reassigning permission but it does not work. I am using GAS Oauth2 library as well. It suddenly happened a few days ago.

I cannot work further due to this. I would appreciate the help.

Hi, guys thanks for trying. I actually found the solution to the problem.

The code 

OAuth2.createService('SERVICE_NAME');

From OAuth2 Library, where the "SERVICE_NAME" is the ScriptUserPropertry, which is saved to the script, had expired. So, I reset it and everything is working fine now.

function run() {

  var service = getDriveService_();

  if (service.hasAccess()) {

    var url = 'https://www.googleapis.com/drive/v3/files?pageSize=1';

    var response = UrlFetchApp.fetch(url, {

      headers: {

        Authorization: 'Bearer ' + service.getAccessToken()

      }

    });

    var result = JSON.parse(response.getContentText());

    Logger.log(JSON.stringify(result, null, 2));

  } else {

    var authorizationUrl = service.getAuthorizationUrl();

    Logger.log('Open the following URL and re-run the script: %s',

        authorizationUrl);

  }

}

fix solution to getAccessToken :)
