Creating new Query Report


To create new query report, do I have been in developer mode?
And to be in developer mode, is it enough to add the “developer_mode”: 1 to the site_config.json file (as my image is production) or I have also to convert from production mode to development mode?
Because currently when I need to create new report, I get the below image.


You can add “developer_mode” : 1 and it should work.
