"Keying set failed to insert any keyframes"

When I try to insert a keyframe all it says is this… If I click in the window and select “insert keyframe” for a material or something it works just fine. However, if I try to delete it from the timeline, it’ll say it deleted it, but it won’t actually do anything. I’m trying to animate the ball to show the effects of the water, and simply pressing “I” gives me this error.

As far as I can see when you press I you are saving to a keying set but there keyset is empty. Either add parameters to the key set or delete it from the Scene settings. Once I do this I can add keyframes (such as Loc) and delete them from the graph editor with X
