This looks like an "error" that might be reported by some kind of software claiming to help with grammar -- the sentence is perfectly correct.
On a side note, you should avoid the temptation to use features in word processing software or online resources that use computer programs to analyse grammar -- they tend to introduce more errors than they remove and also take away the personality of the author. (Spell checkers can be useful if used wisely.) Even the best grammar checker in the world would still be extremely poor compared to a competent copyeditor.
