withdrawStart in POS gives error

[m-a-x-i-m-u-s]

While calling withdrawStart with POSClient an error occurs due to the sender address being undefined.
A solution to the problem is specifying the sender address in the "from" field of second parameter of the withdrawStart function.

this is because you have not provided from value. You can provide from in transaction option or you can provide default value in client.

const result = await withdrawStart(100,{
   from:'from address'
})

or in the client as default from -

 const posClient = new POSClient()
  return posClient.init({
    log: true,
    network: network,
    version: version,
    child: {
      provider: new HDWalletProvider(privateKey, config.child.rpc),
      defaultConfig: {
        from: userAddress
      }
    },
    parent: {
      provider: new HDWalletProvider(privateKey, config.parent.rpc),
      defaultConfig: {
        from: userAddress
      }
    }
  });

this one is more recommended, as it will save you to provide value in each transaction.
