I'm using the Java driver for create a transaction that, then, it's send to our system backend in order to be sent from there.

The assets and the metadata are filled from a valid transaction also received from our backend:

Transaction createTransaction = BigchainDbTransactionBuilder
.init()
.addAssets(transaction.getAsset().getData(), TreeMap.class)
.addMetaData(transaction.getMetaData())
.operation(Operations.CREATE)
.buildAndSignOnly((EdDSAPublicKey) generatedPublic, (EdDSAPrivateKey) generatedPrivate);

sendFulfilledTransaction(createTransaction.toHashInput());

But the message The transaction's id isn't equal to the hash of its body is received when try to send the generated transaction. I think the id is not created correctly by the driver.

Thanks in advance.
