GetFollowers() returning 0 followers

Dec 21, 2015 at 2:27 PM

I have a list of Twitter users and I want to get just 20 followers of each of these users in my list.

I execute User.GetFollowers(20) in a loop. I sometimes do get followers but sometimes get 0 followers. I checked the actual user on Twitter and the user has lots of followers (~ 1500).

I am handling rate limit.
I have a Thread.Sleep(queryRateLimits.ResetDateTimeInMilliseconds) in TweetinviEvents_QueryBeforeExecute event.

Can you please suggest some workarounds or point any mistake in my approach,.
