Ed25519Keypair() Error

[hyungnoh]

Hi guys.

I have installed bigchaindb-driver using command below.
npm install bigchaindb-driver

and I have executed following program code.

const driver = require('bigchaindb-driver')
const API_PATH = 'http://localhost:9984/api/v1/'
const alice = new driver.Ed25519Keypair()

then An error occurred as follows.

TypeError: Expected Buffer
at Object.encode (/home/hyung/node_modules/base-x/index.js:29:41)
at Object.Ed25519Keypair (/home/hyung/node_modules/bigchaindb-driver/dist/node/Ed25519Keypair.js:28:33)

is there anybody knowing this errors?
any suggestions are appreciated.

I had the same problem, the version I got from NPM has a bug in this file:

https://github.com/bigchaindb/js-bigchaindb-driver/blob/master/src/Ed25519Keypair.js

In the NPM package the keys are not transformed to Buffers. You can copy the file to your dev environment and it will work.

In other words, the dev version (master branch) of the JavaScript driver doesn't have this issue.

I'll see about getting a new release into npm. BigchainDB is in a transition phase right now, so that's not as trivial as it sounds.

Any news on this topic?, I still get this error, when I am trying to use it bcdb-driver from npm

Hi Ozan
To resolve the error

1. mv bigchaindb-driver/dist/node
2. vi Ed25519Keypair.js
3. Edit codes
   this.publicKey = _bs2.default.encode(Buffer.from(keyPair.publicKey));
   this.privateKey = _bs2.default.encode(Buffer.from(keyPair.secretKey.slice(0, 32)));

Hi hyungnoh,

Thanks for your help, btw I am using the solution which described in: #265, but I think someone should update npm package, since just changing node files manually is not the best solution(I guess?).

This might be caused by the base-x package being updated. bigchaindb-driver (or one of its dependencies) currently pulls in base-x version 3.0.5. Specifying version 3.0.4 seems to be a workaround for now. e.g.

  "dependencies": {
    "bigchaindb-driver": "^4.1.0",
    "bip39": "^2.5.0",
    "base-x": "3.0.4"
  }

Hi Ozan
To resolve the error

1. mv   bigchaindb-driver/dist/node

2. vi  Ed25519Keypair.js

3. Edit codes
   this.publicKey = _bs2.default.encode(**Buffer.from(keyPair.publicKey)**);
   this.privateKey = _bs2.default.encode(**Buffer.from(keyPair.secretKey.slice(0, 32))**);

Worked for me! Thanks.

Could you make a new release with the version that is in master branch ????

The process to transition the governance of all BigchainDB software to the IPDB Foundation is moving along. I anticipate that they will be able to take care of this soon.
