Cannot upgrade a contract from an impersonated account using ethers with Forking on chain

[nhynhyiddy]

Contract: `

contract Testing {
  function initialize() public initializer {}
  function add( uint256 a, uint256 b) public pure returns(uint256) { return a+b;}
}

`

Reproduce: scripts/testing.ts `

const [_, alice,] = await ethers.getSigners();
const aliceAddress = await alice.getAddress()
console.log("aliceAddress", aliceAddress)
const factory = await ethers.getContractFactory('Foo', alice)
const contract = await upgrades.deployProxy(factory,[])

const impersonate = await ethers.getImpersonatedSigner(aliceAddress)
console.log("impersonate address", await impersonate.getAddress())
const factory1 = await ethers.getContractFactory("Foo", impersonate)
await upgrades.upgradeProxy(contract.address, factory1)  

`

hardhat.config.ts inside networks: `hardhat: { chainId:25,

  forking: {
    url:"https://rpc.vvs.finance",
  },

  accounts: [
    {
      privateKey: <some private key1>',
      balance: "10000000000000000000000",
    },
    {
      privateKey: <some private key2>,
      balance: "10000000000000000000000",
    },
  ]
}

` Error:

Error: VM Exception while processing transaction: reverted with reason string 'Ownable: caller is not the owner'

Scripts: npx hardhat run scripts/testing.ts

If I do not fork on hardhat, contract can be upgraded. but it cannot upgrade with forking.

This issue is also being tracked on Linear.

We use Linear to manage our development process, but we keep the conversations on Github.

Thank you for using Hardhat.

In general, if there is a problem in Hardhat, we will need a minimal reproducible example in order to investigate it. See https://stackoverflow.com/help/minimal-reproducible-example

You have provide some examples here, but they do not correlate well enough to make them reproducible. For example, contract Testing vs Foo; what is upgrades?; etc.

Can you provide us with a minimal reproducible example?

Closing for lack of reproduction steps.
