You can only apply constraints to a vector that has at least as many degrees of freedom as all indices that are referenced in the ConstraintMatrix. Ideally, of course, the vector has an entry for every degree of freedom. I guess you'll have to apply the constraints to a whole block vector, even if you're only interested in block 0.
