com.facebook.sdk error 2 occurs when login to Facebook

Question

I am trying to use Facebook plugin for phone gap but getting error message

"the operation couldn't be completed com.facebook.error 2"

I guess my bundle identifier does not match for Facebook but I am not sure
what I missed for bundle identifier match... check if my code missing something for bundle identifier matching?

deviceready function :

document.addEventListener('deviceready', function() {
     try {
       alert('Device is ready! Make sure you set your app_id below this alert.');
       FB.init({ appId: "120048634820284", nativeInterface: CDV.FB, useCachedDialogs: false });
       document.getElementById('data').innerHTML = "";
     } catch (e) {
            alert(e);
     }
}, false);

info.plist file

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLName</key>
        <string>com.mycompany.myapp</string>
        <key>CFBUndleURLSchemes</key>

Answer 1

I had the same error and finally solved it. The app was configured on Sandbox mode and the facebook user I was using wasn't added to testers group.

An administrator can solve it here: https://developers.facebook.com/apps

Answer 2

Sign out of facebook app from the settings and then try.

This worked for me.
