I'm seeing some issues when I run yarn hardhat deploy-replay hardhat

The expected result is that each mastercopy should be deployed fresh (since it's a brand new network).
Roles, packer, and integrity are giving these errors:

roles
  ✘ Deployment failed:              invalid arrayify value
packer
  ✔ Mastercopy already deployed to: 0xeE557e0E1Bb5BA0c61f9b65287d635cDA323CcAf
