Grafana SSO login redirects to public/build/*.js.map

Grafana suddenly started having this error a couple of days ago when we try to login via SSO and we get Login Failed Internal Server Error. When I look at the console, SSO redirects to a url that matches: https://****.grafana-workspace.us-east-1.amazonaws.com/public/build/1762.43d785e7398c7cdf4250.js.map
