Users/lookup returning over capacity for some users



We are currently having some issues with this particular method. All of our user have less than 30k followers except one, who has over 140k. For each of them we get a sample of 1000 of their followers and we call lookup method for them to get some particular data. So far we haven’t had any troubles, but for this particular user with 140k followers this method is always returning “over capacity” error. Any hints?
