I am sorry you are having this issue. I believe we only saw this previously with the OpenZeppelin CLI. Please note: we’ve decided it’s best to focus our upgradeability efforts on the Upgrades Plugins exclusively, and have halted development on the OpenZeppelin CLI.

Are you using Truffle or Hardhat or is this occurring only with
Can you advise your node and npm version?
Can you share a simple example contract and setup that can be used to reproduce the problem?
Were you able to resolve?

Glad it is resolved.
