reCAPTCHA v3 doesn't return a token when an action specified

[Swapnil Tiwari]

I have integrated reCAPTCHA like so:

1. Added this script - <script src='https://www.google.com/recaptcha/api.js?render=<my-site-key>'></script>
2. Executed this code after the script has loaded:

           grecaptcha.ready(function() {

    grecaptcha.execute('<my-site-key>', {action: 'action_name'})

   .then(function(token) {

       console.log(token)

    });

   });

The console.log statement doesn't print anything in step 2. But when I remove the second parameter { action: 'Page Load' }, from the grecaptcha.execute method, I get a token in my console.

Why is this happening?
The docs don't talk about adding actions anywhere but the directly in the code.
Do I need to configure these actions somewhere before using them in the code?

You are probably using a v2 site key. In the v3 docs it asks you to create a v3 key at this link: https://g.co/recaptcha/v3
