Hi,
You can check with module developer for support if module is paid.
When I have updated my module from version 1.6 to 1.7 , I found this error when module have some compatibility issues with version 1.7.
I fix those issues and then error message gone.
Prestashop 1.7 use Symfony Framework and module need update for this.
