Unable to Stream Money between XRP & ETH Uplink

[rangesh-]

I am trying to use stream money between XRP and Eth using Kavalabs Switch ILP Sdk, but unfortunately I am not able to do the same and please find the code and error logs below, Ideally the anticipated behavior is successful stream of money , but that does not happen .

I did refer the post from Interledger[(https://forum.interledger.org/t/interoperability-prototype-with-moneyd/382/14 )].

Error Logs :

Error: Error verifying tx: tecNO_DST

Code Snippet :

const { connect } = require('@kava-labs/switch-api')
const BigNumber = require('bignumber.js')
async function run() {
const sdk = await connect()
const config = sdk.serializeConfig()

const ethUplink = await sdk.add({
settlerType: 'machinomy',
privateKey: '9d24bf515935e301664aa98639965003321305856bd9caed7bc650f9bc28786d'
});
console.log('**** example-js ****: addING uplink machinomy')
const xrpUplink = await sdk.add({
settlerType: 'xrp-paychan',
secret: 'shiHikLxrjCS6rtuJsLF9cegZQdkk'
});
xrpUplink.balance$.subscribe(amount => {
console.log('XRP interledger balance:', amount.toString())
});

await sdk.deposit({
    /** Uplink to deposit to */
    uplink: xrpUplink,
  
    /**
     * Amount to deposit, in the unit of exchange
     * (e.g. in this case, ether; not gwei or wei)
     */
    amount: new BigNumber(20),
  
    /**
     * Callback to authorize the fee and amount to be transferred from layer 1, after it's calculated,
     * which must return a Promise
     */
    authorize: async ({ fee }) => {
      console.log('Fee:', fee.amount.toString())
  
      // Resolve the Promise continue with the deposit...
      return
  
      // ...or reject the Promise to cancel it:
      throw new Error('Fee too high!')
    }
  })
  ethUplink.balance$.subscribe(amount => {
    console.log('Interledger balance:', amount.toString())
  })

await sdk.streamMoney({
/** Amount to send in units of exchange of the source uplink */
amount: new BigNumber(10),

/** Sending uplink */
source: xrpUplink,

/** Receiving uplink */
dest: ethUplink,

/** Optionally, specify a maximum slippage margin against the most recently fetched exchange rate */
slippage: 0.02

})

}

run().catch(err => console.error(err))

Hello @rangesh-,

Kava's connector may not work, but you could try running your own local connector using connector-config. It requires running Redis, and you'd need to configure/pass these environment variables:

• CONNECTOR_ENV=test
• ILP_ADDRESS=test.<your_name>
• REDIS_HOST=127.0.0.1, REDIS_PORT=6379, REDIS_PASS=<redis password>,
• XRP_SECRET=<XRP testnet account secret> (make sure to use a different account from the one with ilp-sdk)
• XRP_SERVER=wss://s1.ripple.com
• ETHEREUM_PRIVATE_KEY=<ETH private key> -- Ethereum account with funds on Kovan testnet (make sure to use a different one from ilp-sdk)
• ETHEREUM_PROVIDER -- You may need to create an Infura account and pass in the provider URL for the Kovan testnet here

Then, you could try connecting ilp-sdk in local mode to connect to your local connector?
