Product properties should not be accessed directly

Hi,

We are getting this error constantly:
stderr: PHP message: variation_id was called incorrectly.
Product properties should not be accessed directly.

This message was added in version 3.0., referer: https://www.tartaruguita.pt/produto/babete-tamanho-3/

I can’t find exactly where in your plugin to fix it. Can I get help?

Thanks
