What is the correct way to setup hydraulic actuators?

I have a robot with a setup that looks like this.

The red and green are the front and back body. Blue parts are hydraulic actuators and pink parts are revolute joints.
Now if I set up all the joints like this the simulation explodes with errors because its a closed articulation.
What would be the correct way to go about setting this up? I’m fine with turning the robot using the rotation of the middle revolute joint rather than moving the prismatic joints in the hydraulic actuators. But i would still like the actuators move as they should when it does turn.

I tried to set the joints up as shown here but same outcome

Well i found this. Only problem is that my robot is fully dynamic and not glued to the ground like the lamp. Sure removing the rigid body component from the front part makes the joint setup work but that’s not the wanted behavior.

Setting “exclude from articulation” on the joints as shown here seems to have fixed it. To be honest the name of it is at least to me as a non native a bit misleading.
