are you certain the STL stage had the error? In the 3dp discords i'm a part of it seems that i'm continually reminding everyone that slicer features are usually the culprit. Features like 'detect thin walls', 'ensure vertical thickness' and 'extra perimeters if needed' can and will very quickly ruin a print where the STL is error-free. That said, one can accomodate these features by modifying the STL so that the slicer transformation occurs in such a way that allows a usable product, but as far as where the error is introduced, 9 times out of 10 it's the slicer. What should happen is that the slicer should err out to the user when the shape of the end product is predicted to be radically different than the request, but I haven't ran into such features yet. Most slicers just happily try to print stuff that is physically impossible to do, and might be radically different than the shape of the STL -- usually resulting in a plate of spaghetti if you're using an FDM machine.
