OAuthException: Error validating access token: Session has expired on

[ankur bansal]

I am getting the following error on the following code.

FacebookClient facebookClient = new DefaultFacebookClient(MY_ACCESS_TOKEN, MY_APP_SECRET);

User user = facebookClient.fetchObject("me", User.class);

I am using the latest RestFb 1.9 Version

Exception in thread "main" com.restfb.exception.FacebookOAuthException: Received Facebook error response of type OAuthException: Error validating access token: Session has expired on Thursday, 09-Apr-15 17:00:00 PDT. The current time is Thursday, 09-Apr-15 17:37:09 PDT. (code 190, subcode 463)

What am I missing?

Hi ankur,

the access token is expired.

you can check this here: https://developers.facebook.com/tools/debug/access_token/

and the error message tells this, too :)

Cheers

Hi Norbet,

Is there any option of validation token by RestFb?

[Norbert Bartels]

Hi,

you can use the graph api request for access token validation. To do this you need an app access token.

https://developers.facebook.com/docs/facebook-login/access-tokens#debug

Should work with restfb, too. You only need a Facebook Client with a app access token.
