Unable to Open Pool Ledger

[TheArhaam]

So I've run the following and it worked:

const config = {
      genesis_txn: path,
}
const result = await indy.createPoolLedgerConfig('test', JSON.stringify(config));

However, I'm not getting any response (Pool Handle) when opening the pool ledger, I've tried the following:

1. indy.openPoolLedger('test', JSON.stringify(config))
2. indy.openPoolLedger('test', null)
3. indy.openPoolLedger('test', '{}')

Which version of react native are you using?

Could it be related to this issue? Please check if you can reproduce the problem in version 0.61.5 of RN

@TimoGlastra Well myreact-native version is 0.63.2, I will try using 0.61.5 and see if the issue persists. Will get back to you shortly, Thank you 😄

[TheArhaam]

@TimoGlastra I am facing the same issue with react-native version 0.61.5 😭 Have you tested out the rn-indy-sdk completely in your fork?

I've referred to a couple of examples of the Indy SDK and it doesn't seem like I'm missing anything but here is the code I'm currently using:

import React, { Component } from "react";
import { ScrollView, View, Text, TouchableOpacity, StyleSheet } from "react-native";
import indy from 'rn-indy-sdk';
import RNFS from 'react-native-fs';
import axios from "axios";

class App extends Component {

  constructor(props) {
    super(props);
    this.state = {
      wallethandle: null,
      poolhandle: null
    }
  }

  // =========================================
  // FILE SYSTEM
  // =========================================
  getFiles = () => {
    RNFS.readDir(RNFS.DocumentDirectoryPath)
      .then((result) => {
        console.log('GOT RESULT', result);

        // stat the first file
        return Promise.all([RNFS.stat(result[0].path), result[0].path]);
      })
      .catch((err) => {
        console.log(err.message, err.code);
      });
  }

  createGenFile = async () => {
    console.log("CREATE GEN FILE")
    let genesis;
    // get genesis transactions
    await axios.get('http://dev.greenlight.bcovrin.vonx.io/genesis')
      .then(async (res) => {
        genesis = res.data;
        console.log("==================================")
        console.log("GENESIS")
        console.log("==================================")
        console.log(genesis)

        // write genesis to file
        var path = RNFS.DocumentDirectoryPath + '/indy_genesis_transactions.txt';
        console.log("PATH: " + path)
        await RNFS.writeFile(path, genesis, 'utf8')
          .then((success) => {
            console.log('[GEN FILE] WRITTEN!');
          })
          .catch((err) => {
            console.log(err.message);
          });

      })
      .catch((err) => {
        console.log('[AXIOS] ERR: ' + err);
      })
  }

  // =========================================
  // POOL
  // =========================================
  createPool = async () => {
    console.log("CREATE POOL LEDGER CONFIG")
    var path = RNFS.DocumentDirectoryPath + '/indy_genesis_transactions.txt';
    const config = {
      genesis_txn: path,
    }
    console.log("CONFIG: " + JSON.stringify(config))
    const result =
      await indy.createPoolLedgerConfig('test9', JSON.stringify(config))
        .then(async (res) => {
          console.log('POOL LEDGER CONFIG CREATED')
          console.log('Result: ' + res)
        })
        .catch((err) => {
          console.log("ERR: " + err)
        });
  }

  openPool = async () => {
    console.log("OPEN POOL LEDGER")
    var path = RNFS.DocumentDirectoryPath + '/indy_genesis_transactions.txt';
    const config = {
      genesis_txn: path,
    }
    console.log("CONFIG: " + JSON.stringify(config))
    await indy.openPoolLedger('test9', '{}')
      .then((res) => {
        console.log('POOL LEDGER OPENED');
        console.log('POOL HANDLE: ' + res);
        this.setState({
          poolhandle: result
        })
      })
      .catch((err) => {
        console.log('OPEN POOL ERR: ' + err);
      });
  }

  render() {
    return (
      <ScrollView>
        {/* CREATE GEN FILE */}
        <TouchableOpacity onPress={() => { this.createGenFile() }}>
          <View style={styles.bttn} >
            <Text style={styles.txt}>Create Gen File</Text>
          </View>
        </TouchableOpacity>
        {/* GET FILES */}
        <TouchableOpacity onPress={() => { this.getFiles() }}>
          <View style={styles.bttn} >
            <Text style={styles.txt}>Get Files</Text>
          </View>
        </TouchableOpacity>
        {/* CREATE POOL LEDGER CONFIG */}
        <TouchableOpacity onPress={() => { this.createPool() }}>
          <View style={styles.bttn} >
            <Text style={styles.txt}>Create Pool Ledger Config</Text>
          </View>
        </TouchableOpacity>
        {/* OPEN POOL LEDGER */}
        <TouchableOpacity onPress={() => { this.openPool() }}>
          <View style={styles.bttn} >
            <Text style={styles.txt}>Open Pool Ledger</Text>
          </View>
        </TouchableOpacity>
      </ScrollView>
    );
  }

}

// STYLES - STYLESHEET
const styles = StyleSheet.create({
  bttn: {
    backgroundColor: 'lightblue',
    padding: 20,
    margin: 20
  },
  txt: {
    color: 'black',
    textAlign: 'center'
  }
});

export default App;

NOTE: I've tried the following for openPoolLedger() :

1. indy.openPoolLedger('test', JSON.stringify(config))
2. indy.openPoolLedger('test', null)
3. indy.openPoolLedger('test', '{}') Not really sure which one is correct.

I'm able to reproduce your error in RN > 0.61.5, but not 0.61.5. However i'm using the master version of rn-indy-sdk instead of the NPM version. So could you check once again, but this time with version 0.65.1 and the master branch? To run with the master branch:

git clone https://github.com/AbsaOss/rn-indy-sdk
cd rn-indy-sdk
yarn install
yarn pack

this will output a file rn-indy-sdk-v0.1.3.tgz that you can then add to your react native project. Inside your react native project run:

yarn add file:../path/to/rn-indy-sdk/rn-indy-sdk-v0.1.3.tgz

---

Do note that the master branch doesn't expect strings as parameters, but JSON objects:

// NPM rn-indy-sdk
indy.createPoolLedgerConfig('test9', JSON.stringify(config))

// master rn-indy-sdk
indy.createPoolLedgerConfig('test9', config)

For the openPoolLedger it is fine to call without a second parameter (openPoolLedger('test9')). Also make sure to call setProtocolVersion(2) before opening the pool.

Working example

```javascript import {View, Text} from 'react-native'; import React, {useEffect} from 'react'; import indy from 'rn-indy-sdk'; import axios from 'axios'; import RNFS from 'react-native-fs'; const App = () => { useEffect(() => { async function internal() { const walletId = `test-wallet-${Math.random()}`; console.log('walletId', walletId); const poolName = `test-pool-${Math.random()}`; console.log('poolName', poolName); await indy.createWallet({id: walletId}, {key: 'test'}); const walletHandle = await indy.openWallet({id: walletId}, {key: 'test'}); console.log('walletHandle', walletHandle); const response = await axios.get( 'http://dev.greenlight.bcovrin.vonx.io/genesis', ); const genesisPath = RNFS.DocumentDirectoryPath + '/genesis.txn'; console.log('genesisPath', genesisPath); await RNFS.writeFile(genesisPath, response.data, 'utf8'); const config = { genesis_txn: genesisPath, }; await indy.createPoolLedgerConfig(poolName, config); await indy.setProtocolVersion(2); const poolHandle = await indy.openPoolLedger(poolName); console.log('poolHandle', poolHandle); } internal(); }, []); return ( Hello World ); }; export default App; ```

Let me know if you can get it to work!

[TheArhaam]

@TimoGlastra Thank you for all your help, turns out all I had to do was add indy.setProtocolVersion(2) 😅. It's working now, I was able to get the Pool Handle. I'm not sure what this function does, I would appreciate it if you could give me a brief explanation 😅

Also, would you recommend I use the master branch going forward? Or should I stick to the current npm package?

[TimoGlastra]

For the protocol version, see the indy-sdk docs. It defaults to 1. From the docs: "Protocol version will be used: 1 - for Indy Node 1.3 2 - for Indy Node 1.4 and greater". I believe indy node version is already at something like level 1.12, so you'll probably always need version 2.

For using the master branch: I would say yes at the moment. The NPM package isn't updated in a while, and as the package is in early stage development you'll probably get the fixes quicker

[TheArhaam]

@TimoGlastra Alright, thank you so much for all the help. 😄
