Does anybody experience extending the core on sites that utilize extensions? I thought you could just a run a

gulp local

, but I keep getting an error, even when I run it on the

master

branch of our repo (that I know works)

shopping-local.ssp:99 GET <https://staging.XXXXXX.com/ssp-application-name/shopping-templates.js?t=1591061000476> net::ERR_ABORTED 404

Anybody know what that’s about?
