* Returns the revert reason generated by the EVM if the transaction were to be executed.

* @param web3Context - ({@link Web3Context}) Web3 configuration object that contains things such as the provider, request manager, wallet, etc.
* @param transaction - A transaction object where all properties are optional except `to`, however it's recommended to include the `from` property or it may default to `0x0000000000000000000000000000000000000000` depending on your node or provider.
* @returns `undefined` if no revert reason was given, a revert reason object, a revert reason string, or an `unknown` error
