User properties not set on Identify

Hi, I have a new amplitude installation on my website and I’m not able to get user properties to show up in amplitude. I am migrating from Heap. Sessions and events are being tracked in amplitude, just without any user properties (ie. “email”).

In my code I have:

<script type="text/javascript">
    const properties = {
        plan: '3',
        payment_method: 'stripe',
        account_type_id: '1',
        profile_complete: '1',
        handle: 'test',
        dashboard_url: 'https://test.com/dashboard/',
        company_id: '1',
        company_name: 'test',
        joindate: '1245300441',
        contact_name: 'test test',
        first_name: 'Test',
        last_name: 'Test',
        user_id: '1',
        email: 'test@test.com',
        billing_frequency: 'month',
    };
    if (window.amplitude){
        const identifyEvent = new window.amplitude.Identify();
        identifyEvent.set(properties);
        window.amplitude.identify(identifyEvent);
    }
</script>

What I see in the network tab is an empty user_properties object:

Based on some other threads, I thought the issue might be that I need to pre-define these user properties in the Amplitude dashboard. I did that and it’s still not working.

Please help!

Thank you
