I’m trying to give you with as much information as I can get out of my logs.
It doesn’t happen always, but minimum once or twice a day. According to my logs last time it happened was January 06 08:14:37 GMT +1. It lasted about a minute. All requests in this timeframe returned 0 followers and no error.
I mentioned earlier that absolutely no errors were thrown by the API but it seems like that’s wasn’t true. At Jan 06 08:13:51 GMT +1 the request returned the following error.
{“error”:“Internal Server Error”,“status”:500,“message”:""}
Not really helpful to me, but maybe your logs give you a better insight into what happened.
After that error the API returned an empty followers array on every request for about a minute (instead of continuing to give me an error that I can handle gracefully), doesn’t matter if I start fetching the followers from scratch or if I fetch them from another user. Everyone has an empty followers array.
