Hi all, I get the following error while running the gen_pdn command:
Error: pdn.tcl, 17 TypeError in method 'microns_to_dbu', argument 1 of type 'double'
I searched for the openlane installation and the project directories; however found nothing that flags this error. Is there anyone that encountered this issue before?

I'll try and let you know about the results.
Modifying OpenLane commit id in the project breaks something in the flow:
[ERROR]: The version of open_pdks used in building the PDK does not match the version OpenLane was tested on (installed: 7519dfb04400f224f140749cda44ee7de6f5e095, tested: 41c0908b47130d5675ff8484255b43f66463a7d6)

I faced with this one too: in the openlane/dependencies/toolmetadata.yml changed ID of pdk with installed one and it worked.
