Ganache hash doesn't match Web3j response with error `TxHashMismatchException`

Question

When trying to run any transaction using Web3j on Ganache it fails with the exception: TxHashMismatchException. It seems that something has changed on Ganache that is breaking the interoperability.

Answer 1

The issue here is that Ganache has changed the way the transactions hashes are created since version 6.2.0. This problem doesn't exist on version v6.1.8 and earlier, using v6.1.8 should fix your issue.

If you are running Ganache using Docker make sure that you specify the version and not latest.
