QVX_UNEXPECTED_END_OF_DATA for Qlik Sense Desktop

[dialika_bantog]

Hi Guys!

I'm using Qlik Sense Nov. 2018 version. Any bright ideas on why I am encountering the error below? I'm trying to get data from Facebook. 

QVX_UNEXPECTED_END_OF_DATA: The connection format is obsolete. Please edit your connection object and save it.

Appreciate any help.

Cheers!
