WrapObject Error Message Matlab

[Pelle Heun]

Hi,
I am having an issue with the code I have created. I am trying to wrap the muscles around the sphere, so they don't clip through the geometry. I am following these posts

Even though I copied the code word for word, when I try to open the Model in OpenSim, I receive an error message:
"Failed to connect Socket 'parent_frame' of type PhysicalFrame (details: Connectee for Socket 'parent_frame' of type PhysicalFrame in PathWrapPoint at /forceset/MedialRectus/geometrypath/Eye/pwpt1 is unspecified. If this Model was built programmatically, perhaps finalizeConnections() was not called before printing.
Thrown at Component.h:3345 in finalizeConnections().)
In Object 'pwpt1' of type PathWrapPoint.
Thrown at Component.cpp.313 in finalizeConnections()."

As you can see in the code, I called finalizeConnections(), so I am unsure where the error lies. I could imagine either that the component path is unclear or there is some other issue with adding the wrap object to the muscle.
I would appreciate any input.

Thank you,
Pelle
