URL Query Parameter errors starting occurring on 12/24

On 12/24 we started getting errors in FB Biz Manager for URL Paramters that PixelYoutSite is generating for first_name, last_name, and payer_email for PageView and Purchase events.

The error states that you’re allowed to send these parameters to FB but that it “must be setup correctly”
