QuorumJS Private Signed Transactions not working about quorum.js HOT 5 CLOSED

Hey @golashr the enclave exposure has been removed, you should instead pass in enclave options like so:

const enclaveOptions = {
  /* at least one enclave option must be provided */
  /* ipcPath is preferred for utilizing older API */
  ipcPath: "/quorum-examples/examples/7nodes/qdata/c1/tm.ipc",
  publicUrl: "http://localhost:8080",
  privateUrl: "http://localhost:8090"
};

const rawTransactionManager = quorumjs.RawTransactionManager(web3, enclaveOptions);

I do see that we mention it in documentation and will clean up in a bit.

from quorum.js.

Hey @fixanoid thanks for the reply, I used the enclaveOptions and the rawTransaction manager as follows
`const Web3 = require('web3')
const EthereumTx = require('ethereumjs-tx');
const ethUtil = require('ethereumjs-util');
const quorumjs = require("quorum-js");
const methodData = require('../method'); // contains the encoded method call to a contract

const h1 = "http://localhost:8545";
const c1 = "http://localhost:10000";
const w1 = new Web3(new Web3.providers.HttpProvider(h1));
const enclaveOptions = {
ipcPath: null,
publicUrl: h1,
privateUrl: c1
};
const privateKey = [
"ac99871291b922f6d04bd3d0f1c64829929704e466e120687aa674b62156bbe5",
"8d6149179469b8fabfeb6e076495bcf1cb47d5bf8b5f18947fa2fae1f74ad63b"
];
const fromAccountAddress = '0x' + ethUtil.privateToAddress("0x" + privateKey[0]).toString('hex');
var pk = "OZA1sYnJnJ3E4g1APBzRCn0B+otLSRNOnD6+GzYXfgo=";
var pk2 = "axuKyW5/BnVP+g+rTXLmWLhNwOk9tcaCKWSiW3xK+FA=";
const rawTransactionManager = quorumjs.RawTransactionManager(w1, enclaveOptions);
const ntxnParams = {
gasPrice: 0,
gasLimit: 4700000,
value: 0,
data: methodData,
from: {
privateKey: '0x' + privateKey[0]
},
privateFrom: pk,
privateFor: [pk2],
nonce: 0
};
w1.eth.getTransactionCount(fromAccountAddress, 'pending', (err, nonce) => {
ntxnParams.nonce = nonce;
console.log("Nonce :", nonce);
rawTransactionManager.sendRawTransaction(ntxnParams)
.then((b) => {
console.log("success");
console.log(b);
})
.catch((e) => {
console.log("Error Thrown : ");
console.log(e);
});
});`

and for some reason I keep getting the following error

Nonce : 1 Error Thrown : Error: Returned error: invalid argument 0: json: cannot unmarshal non-string into Go value of type common.Hash at Object.ErrorResponse (/home/vivek/dev/quorum/Apps/Test/node_modules/web3-core-helpers/src/errors.js:29:16) at /home/vivek/dev/quorum/Apps/Test/node_modules/web3-core-requestmanager/src/index.js:140:36 at XMLHttpRequest.request.onreadystatechange (/home/vivek/dev/quorum/Apps/Test/node_modules/web3-providers-http/src/index.js:91:13) at XMLHttpRequestEventTarget.dispatchEvent (/home/vivek/dev/quorum/Apps/Test/node_modules/xhr2-cookies/dist/xml-http-request-event-target.js:34:22) at XMLHttpRequest._setReadyState (/home/vivek/dev/quorum/Apps/Test/node_modules/xhr2-cookies/dist/xml-http-request.js:208:14) at XMLHttpRequest._onHttpResponseEnd (/home/vivek/dev/quorum/Apps/Test/node_modules/xhr2-cookies/dist/xml-http-request.js:318:14) at IncomingMessage.<anonymous> (/home/vivek/dev/quorum/Apps/Test/node_modules/xhr2-cookies/dist/xml-http-request.js:289:61) at emitNone (events.js:111:20) at IncomingMessage.emit (events.js:208:7) at endReadableNT (_stream_readable.js:1064:12) at _combinedTickCallback (internal/process/next_tick.js:138:11) at process._tickCallback (internal/process/next_tick.js:180:9)

Can you please let me know what I am doing wrong, or what is the right way to send a signed private transaction ? Thank You in advance

from quorum.js.

Hey @golashr, theres a bit of prerequisite knowledge that may be missed when reading our docs -- this will go away in the near future, but read on for the explanation.

Depending on the transaction manager and quorum version you are using, you may need different API call. For c11n [constellation] with any quorum version, you must only define ipcPath and nothing else. Then the call you can use is rawTransactionManager.sendRawTransactionViaAPI(txnParams) -- the other call rawTransactionManager.sendRawTransaction(txnParams) will fail because c11n does not support required server API.

You may also use the sendRawTransactionViaAPI with any version of tessera and quorum, but your enclave option must define public and private URLs only.

Finally, to use sendRawTransaction proper, you must have configured tessera v0.8+ and quorum v2.2.1+. A working example is provided here: https://github.com/jpmorganchase/quorum-examples/tree/master/examples/7nodes/samples

So, in the code you have, simply try modifying sendRawTransaction to sendRawTransactionViaAPI and see if it works, otherwise follow the example from quorum-examples send via quorum.js

from quorum.js.

I was able to send private transactions using sendRawTransactionViaAPI, still facing difficulty accessing the deployed contract though. But I don't think that has anything to do with quorum js. Thanks for your response

from quorum.js.

yes @bvivek777, Consensys/tessera#658 is another query that we are waiting for the response.
