Error while sharing to facebook

Hello.

I get an error when trying to share the customization done on Zakeke via facebook share.
All I get is a white window with an error.
There is a popup but no image shown.

There is also this url shown https://virtusfootball.com//?wc-ajax=zakeke_share&path=/share/2020/12/08/648482fe-e865-4242-9c92-50c7e901dcd9 as a src to the image.

Could you please help ?
