Hi ,
I am newbie in prestashop 1.7.2.1. I created a module for product enquiry. In that module I have created a controller to display the grid view in the enquiry tab in Back office. But when I am opening Enquiry tab in admin panel it's giving me the following error(screenshot attached). I am also attaching my controller named AdminEnquiryController.php for refrence. apart from this can any one let me know, Is $this->fields_list will display the grid view automatically or do I need to implement this(if yes then how?)
I am stucking in this, couldn't find solution. Thanks in advance,please help.
