How to make a contract inheriting ChalinkClient UUPS upgradable?

Getting the error below when deploying the contract on the local hardhat network. How is it supposed to be made upgradeable?

I think this is something Chainlink guys are already discussion and is an open issue:

So, for now, no way to make a contract using Chainlink upgradeable safely?

:1234: Code to reproduce

  1) MyContract
       "before all" hook for "Retrieves the version":
     Error: Contract `MyContract` is not upgrade safe

@chainlink\contracts\src\v0.8\ChainlinkClient.sol:32: Variable `requestCount` is assigned an initial value
    Move the assignment to the initializer

Hardhat

As far as I can see from the links you provided here it is not possible to use the Chainlink contracts in an upgradeable context (UUPS or otherwise).
