I am developing a React application for my company in which we have the requirement to import some Qlik Sense objects from an app. I tried to use Enigma.JS but couldn't make it work, so I opted for another approach. Since it's my first time working with Sense, I followed along this awesome post by @Francis_Kabinoff
I think it's because your mashup server is http, not https. Look atthe request for the qlik.js file, it's http:// not https://, and that's probably because in your config, the isSecure is set by checking window.location.protocol. You can try just setting isSecure to true, or try switching your mashup server to https.
