[Err] [SDFFeatures.cc:728] Asked to create a joint between links as parent and as child, but the child link already has a parent joint of type [RevoluteJoint].

I tried to run sdf file using ignition but I got this error, my SDF file is a 4 bar linkage mechanism so it need to have 2 parents and in the follower bar. Do any one got a solution
