I can't catch Facebookexceptions in try catch block

[GQwebsites]

I'm having an issue catching the proper exception, no matter what i do i get the same response. This is the response i get in the view Error validating access token: The user has not authorized application FacebookResponseException in FacebookResponseException.php line 89:

The issue arrises after a user de-authorizes my app from Facebook after have created an access_token , what I ant to do is catch the exception and automatically log them out and flush the session: But i can't seem to find the right exception to catch I've tested with all these: I narrowed the problem to being inside this catch block: I included the catch block, then the full code I'm using in my route's function after.

 `      try {
        // Returns a `Facebook\FacebookResponse` object
        $response = $fb->get('/me?fields=permissions');
        } catch(Facebook\Exceptions\FacebookResponseException $e) {
        echo 'Graph returned an error: ' . $e->getMessage();
        exit;
        } catch(Facebook\Exceptions\FacebookSDKException $e) {
        echo 'Facebook SDK returned an error: ' . $e->getMessage();
        exit;
        } catch(Facebook\Exceptions\FacebookAuthenticationException $e) {
        echo 'Facebook Dan1 returned an error: ' . $e->getMessage();
        exit;
        } catch(Facebook\Exceptions\FacebookAuthorizationException $e) {
        echo 'Facebook Dan2 returned an error: ' . $e->getMessage();
        exit;
        } catch(Facebook\Exceptions\FacebookClientException $e) {
        echo 'Facebook Dan3 returned an error: ' . $e->getMessage();
        exit;
        } catch(Exception $e) {
        echo 'Facebook Dan4 returned an error: ' . $e->getMessage();
        exit;
         }`

now my full code for this page:

`   
public function getHomeProfile(Request $request, LaravelFacebookSdk $fb) 
{
    $user = Auth::user();

    $token = Session::get('fb_user_access_token');

     // $fb->setDefaultAccessToken($token);
     // $resp = $fb->get('/debug_token?=input_token=$token');
    // dd($resp);

    $permissionsToRequest = ([
        'public_profile',
        'publish_actions'
    ]);

    $login_link_for_public_actions = $fb->getLoginUrl($permissionsToRequest, 'http://pms.dev:8000/facebook/publicactions/callback');

    if (isset($token)) {

        $fb->setDefaultAccessToken($token);

        // $debugToken = $fb->get('/debug_token?input_token=' . $token);
        // $debugTokenResponse = $debugToken->getGraphNode()->asArray();

        // echo "<pre>";
        // print_r($debugTokenResponse);
        // echo "<pre>";

        // die();
        try {
        // Returns a `Facebook\FacebookResponse` object
        $response = $fb->get('/me?fields=permissions');
        } catch(Facebook\Exceptions\FacebookResponseException $e) {

Hey @GQwebsites! You're already catching the FacebookResponseException. You just need a method to do everything you mentioned after you catch the exception:

try {
    $response = $fb->get('/me?fields=permissions');
} catch(\Facebook\Exceptions\FacebookResponseException $e) {
    $this->doOtherStuff();
    return;
}

@SammyK Thanks, but the problem I'm facing is that no matter what I do after i catch the exception, the code I put in the catch block won't run. here's what i did to test:

try { $response = $fb->get('/me?fields=permissions'); } catch(\Facebook\Exceptions\FacebookResponseException $e) { dd('Test Run'); return; }

and i still get the same response : FacebookResponseException in FacebookResponseException.php line 89: Error validating access token: The user has not authorized application

I know why the exceptionr is getting thrown, its after a user de-authorizes my app. What I can't seem to do is trigger a method to run inside my catch block if the FacebookResponseException is hit.

@SammyK OK I solved it, i didn't know i needed to add use Facebook; to the namespace, all i added was use SammyK\LaravelFacebookSdk\LaravelFacebookSdk;

its all working good now, not sure if mentioned it in the documentation, if you did I must of missed it.
