The
whatwg-fetch
polyfill kicks in in IE11, and it doesn't support non-transparent redirection, or theredirected
flag, sinceXmlHttpRequest
follows redirects without any indication to the caller. So this changes to request JSON so the server responds with a 401 instead and avoids the issue.This also updates the instrumentation, and makes a noop refactor to
apiFetchJson
to expose the plain method.
