How to fix?
Upgrade @openzeppelin/contracts-upgradeable to version 4.3.3 or higher.
Overview
@openzeppelin/contracts-upgradeable is a Secure Smart Contract library for Solidity.
Affected versions of this package are vulnerable to Numeric Errors. When ERC1155 tokens are minted, a callback is invoked on the receiver of those tokens, as required by the spec. When including the ERC1155Supply extension, the total supply is not updated until after the callback, thus during the callback the reported total supply is lower than the real number of tokens in circulation.
