title: Chrome App - Identity API - Bad client ID NON_NATIVE
body: <p>I'm getting this weird error and I haven't seen it anywhere else. When I try to call <code>chrome.identity.getAuthToken</code>, I get back <code>undefined</code> (which means an error occurred) and a <code>chrome.runtime.lastError</code> that says <code>Oauth2: bad client id NON_NATIVE</code>. I have no idea what that means (I put my Oauth client id into the <code>manifest.json</code> just like in the examples) and I haven't seen this error anywhere else.</p>
