Hello,
I am attempting to use the new mediarequests API with tutorial at https://wikitech.wikimedia.org/wiki/Analytics/AQS/Mediarequests

However either the service or the examples are broken. When I attempted to access the example:

https://wikimedia.org/api/rest_v1/metrics/mediarequests/per-file/all-referers/all-agents/%2Fwikipedia%2Fen%2F0f%2F6f%2Fmanolo.jpg/monthly/2018010100/2019010100

I get the error:

"The date(s) you used are valid, but we either do not have data for those date(s), or the project you asked for is not loaded yet. Please check https://wikimedia.org/api/rest_v1/?doc for more information."
