CloudFlare Stream API Error: "redis: nil"


#1

Attempting to upload a video using Tus. As far as I can tell, all headers are correct, but CloudFlare is giving me a relatively useless error message:

Server error: PATCH https://api.cloudflare.com/client/v4/zones/d8c7bdef2859841858bf815bad5a3249/media/5bc79d89ad882 resulted in a 500 Internal Server Error response:
redis: nil

What is “redis: nil”? How can I debug this further?
