This warning is displayed when the upper and lower limits of the keyform set in the art mesh that is the source of the clipping mask do not exist, or when this art mesh is hidden.
If the upper and lower limits of the keyform of the art mesh in question do not exist, set the keyform, or if the art mesh is hidden, make it visible to clear the warning.
