404 Error found for unknown file

I can see in the Network tab of Chrome's developer tools that a 404 error is being recorded for the following file /Themes/<<themename>>/Content/CSS/none. There is no file or folder matching this and I cannot find any reference to this. It seems to be coming from the following which I'm not sure where this is q_ev5pvrk7dmjut-ul379indtzo9b5ya8m1xisonl581.js?v=Q4YVkCwDB7u7U9A40PcL2n5Qgk-bd1VpgF8NiooYx8E1:1

I don't see any issues with the site however I'd like to know how and why this is appearing?

We are using nopCommerce 3.2 and the Lighthouse theme

Hi jvadakkel,

If you could share a link to your web site then it would be easier to see what is this and advice.
You can try disabling the javascript bundling, so that you can see which is the script that looks for the missing file.

Thanks

Hi Boyko

Right now we haven't deployed it to production so I can't share a URL quite yet. How do i disable the javascript bundling? Through web.config?

It appears to be coming out of the jquery-1.7.1.min.js file
