How do I solve a skel is not defined at skel-layers-min.js django framework error

Question

Hello there my fellow devs. I am a backend beginner Django developer and I used a premade template from Htmlup.com. I have changed all the links to {'static "{file location}"'}. When I run it on localhost it gives me this error:

init.js:15 Uncaught TypeError: {(intermediate value)} is not a functionat init.js:15

I have tried adding:

var helios_settings = {
    //other settings here
    skel: {prefix: "{% static '/css' %}" },
    // other settings here
}

to the init.js file but it's still not working. Please help me with the issue.
