deformable element nodes contained in node set ErrNodeRotNodeNoRotInert have no rotary inertia

Hey, i  am doing an impact analysis of a container. I have provided connector
Assembled complex (Beam) in between container lid lid an container bottom
part. beam will serve as Bolt between them. I have provided an initial
velocity to container assembly and also modeled a rigid part at which it
will drop. During analysis i am receiving this error.
The deformable element nodes contained in node set ErrNodeRotNodeNoRotInert
have no rotary inertia associated with them and some rotational degrees of
freedom at the nodes are not constrained. Either rotary inertia must be
defined or all of the rotational degrees of freedom must be constrained"
