Describe the bug

When I try to run make DESIGN_CONFIG=./designs/sky130hd/chameleon_hier/config.mk, I am getting an error.

Have you tried "Check the congestion heatmap in the GUI and load ./reports/sky130hd/chameleon_hier/base/congestion.rpt in the DRC viewer."?

Similarly to https://github.com/The-OpenROAD-Project/OpenROAD/issues/3321 not a CI'ed design

@vijayank88 do you want to pursue this?
