如何批量上传，批量支付，批量铸造？

[BBQFIL]

require('dotenv').config('./.env')
const fs = require('fs').promises
const { mcsClient } = require('mcs-client')
const client = new mcsClient({
  privateKey: process.env.PRIVATE_KEY,
  rpcUrl: process.env.RPC_URL,
})

async function main() {
  const fileArray = [
    { fileName: 'AAAA', file: await fs.readFile('./AAAA') },
    { fileName: 'BBBB', file: await fs.readFile('./BBBB') },
    { fileName: 'CCCC', file: await fs.readFile('./CCCC') },
  ]

  const options = {
    delay: 1, 
    duration: 525, 
    fileType: 0, 
  }

  const uploadResponses = await client.upload(fileArray, options)
  console.log(uploadResponses)
  const payloadCid = uploadResponses[0].data.payload_cid
  const tx = await client.makePayment(payloadCid, '0.002')
  console.log(tx.transactionHash)

  const nft = {
    name: 'NFT', 
    description: 'NFT',
    image: uploadResponses[0].data.ipfs_url,
    tx_hash: '0x...',
  }

  const mintTx = await client.mintAsset(payloadCid, nft)
  console.log(mintTx)  
}

main()

这样写只能批量上传，但是只有第一个文件被支付和铸造。
应该怎么改？ @rykci
