Assets not loading to page: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

Hi there, 

We are trying to load a test variant to the page but it's not displaying. Currently getting the error below in the console, the assets seem to be 404'ing out. 

Wondering if anyone has had experience with this same issue?

"DevTools failed to load source map: Could not load content for https://PAGE/etc/designs/zg/PAGE-com-rebrand/desktop/js.asset.js/core/math.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE"

Thanks in advance for the help!
