TypeError: gapi.auth2.grantOfflineAccess is not a function
Question
I am initializing gapi.auth2 in my index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<meta name="google-signin-client_id" content= "817677528939-dss5sreclldv1inb26tb3tueac98d24r.apps.googleusercontent.com">
<meta name="google-signin-scope" content="profile email">
<script src="https://apis.google.com/js/client:platform.js?onload=start" async defer></script>
<script>
function start() {
console.log('script running')
gapi.load('auth2', function() {
auth2 = gapi.auth2.init({
client_id: '817677528939-dss5sreclldv1inb26tb3tueac98d24r.apps.googleusercontent.com',
scope: 'profile email'
});
});
}
</script>
<!-- <meta name="theme-color" content="#000000"> -->
<!-- <link rel="manifest" href="%PUBLIC_URL%/manifest.json"> -->
<!-- <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico"> -->
<title>React App</title>
</head>
<body>
<div id="root"></div>
</body>
</html>
Then in my react app:
At the top of the page: /* global gapi */
handleSignIn() {
console.log(gapi.auth2)
gapi.auth2.grantOfflineAccess()
}
the console.log is printing:
{init: ƒ, authorize: ƒ, _gt: ƒ, enableDebugLogs: ƒ, getAuthInstance: ƒ, …}
so it looks like gapi.auth2 is a function, but I'm getting the error:
gapi.auth2.grantOfflineAccess is not a function
What am I doing wrong?

It looks like you are not calling grantOfflineAccess on the GoogleAuth object. To get the GoogleAuth object, you need to call getAuthInstance() like so:
var ga = gapi.auth2.getAuthInstance();
ga.grantOfflineAccess();
Make sure you only call getAuthInstance() after first calling gapi.auth2.init() as specified here .

Missed a step:
looking at the function that was printed I needed to call another function first:
gapi.auth2.getAuthInstance().grantOfflineAccess()
