Error:assert(abs(revolute1.r_rel_a[3])<=1e-10) was triggered:

The MultiBody.Joints.RevolutePlanarLoopConstraint joint is used as cut-joint of a
planar loop. However, the revolute joint is not part of a planar loop where the
axis of the revolute joint (parameter n) is orthogonal to the possible movements.
Either use instead joint MultiBody.Joints.Revolute or correct the
definition of the axes vectors n in the revolute joints of the planar loop.

想做一个简单的机构但是提示平面环出问题了，上官网找平面环处理但是个人版没找到平面环工具，能帮我看一下哪里出问题了吗？以下是简图和mo文件
