[SOLVED] Deleting Springs via SofaPython3

Dear SOFA Community,
I am trying to simulate two objects that are connected via connective tissue.
The easiest way to achieve a similar behavior is a StiffSpringForceField.
I would like to delete springs in this ForceField, when a certain force on the objects is exceeded. (Look into the mechanical object at specific indices, and trigger spring deletion, once force is too large.

body1.addObject(
    "StiffSpringForceField",
    template="Vec3d",
    name="SpringForceField",
    object1=body1.collisionMO.getLinkPath(),
    object2=body2.collisionMO.getLinkPath(),
    indices1=[78, 34],
    indices2=[88, 96],
    length=[28.4112, 29.8606],
    stiffness=1e04,
    damping=5
    )
body1.init()

When I create the scene via runSofa, the springs are visible in the object, and removing them during runtime works fine.

As a next step, I wanted to do the same thing from within a python script.
However, print(body1.SpringForceField.spring.value) returns [[], []] So the general shape of the DataField is correct, but I cannot access the springs.

What would be your approach to delete springs via python?
Deactivating all springs at once with body1.SpringForceField.isCompliance = True works fine, but I would like to delete individual springs.

Cheers,
Paul
