SurfaceGripper | DcDestroyD6Joint: Invalid or expired D6 Joint handle

Hello, I’m having trouble with my Surface Gripper.
It’s not opening successfully to open gripper (catch objects).
I encounter the error message
‘DcGetD6JointConstraintIsBroken: Invalid or expired D6 Joint handle’
‘DcDestroyD6Joint: Invalid or expired D6 Joint handle.’

Can anyone help me figure out how to resolve this issue? Thanks!!

@lily.chen could this thread provide some insight given the similarities of the error messages?

Yes. The Same Error Message,
But I didnt add any Joint into my object (The Post),
my gripper still can’t open successfully (catch objects).
