I get:

[0] No support for this operation for this object type
[0] Local to Global scattering with INSERT_VALUES is not supported for single rank in a direction with boundary conditions (e.g. periodic) inducing a non-injective local->global map. Either change the boundary conditions, use a stencil width of zero, or use more than one rank in the relevant direction (e.g. -stag_ranks_x 2)
