Hello Odoo Community,

I hope this message finds you well. I'm encountering a specific issue related to variant images and prices on my Odoo website. The problem is as follows:

ISSUE DESCRIPTION:

When logged in as an administrator, I can see that the variant images and prices update correctly on the product page of website when I click on different attribute values (as you can see in the link below):

However, when I try as a public user, the prices and images on the product page of website do not get updated(as you can see in the link below):

I see as main difference that in the public user case I have this message: "odoo.http: Session expired".

The version of odoo is equal to 16.

Your insights and guidance are highly appreciated. Thank you in advance for your assistance.
