Just added console.log to check the version within getWeb3.js

import Web3 from 'web3'

const resolveWeb3 = (resolve) => {
  let { web3 } = window
  
  const alreadyInjected = typeof web3 !== 'undefined' // i.e. Mist/Metamask
  const localProvider = `http://localhost:9545`

  if (alreadyInjected) {
    console.log(`Injected web3 detected.`)
    console.log('web.version =', web3.version)
    web3 = new Web3(web3.currentProvider)
  } else {
    console.log(`No web3 instance injected, using Local web3.`)
    const provider = new Web3.providers.HttpProvider(localProvider)
    web3 = new Web3(provider)
  }
  console.log('web.version =', web3.version)
  
  resolve(web3)
}

Seems like it's not getting the correct network ID? Have a look at this: https://github.com/adrianmcli/truffle-next/blob/master/client/lib/getContract.js#L3-L4

Actually I already use this = your code.
I ended up doing the truffle unbox again, merged my code back in and somehow it solved the problem.
Now I just can't get my contract calls to works, although they look the same as your example store/get.

newVehicleToken = async () => {
    const { accounts, contract } = this.props
    const model = 'Porsche Cayenne'
    const vin = 'WP1AB29P64LA63732'
    const ein = 'AFD'
    const tokenId = await contract.methods.mintNewVehicleToken(
      web3.utils.utf8ToHex(model), 
      web3.utils.utf8ToHex(vin), 
      web3.utils.utf8ToHex(ein)).send({ from: accounts[0] })
    this.setState({ lastTokenId: tokenId })
  };

  getVehicleData = async () => {
    const tokenId = 1;
    const { accounts, contract } = this.props
    const response = await contract.methods.getVehicleData(tokenId).call({ from: accounts[0] })
    console.log('getVehicleData(1) : response =', response)
    this.setState({ model: response[0], vin: response[1], ein: response[2] })
    console.log('model =', this.state.model)
  };

newVehicleToken comes back with a strange error

2nd get.. likely does not work for same reason or because their is no data yet.

Just in case if you have some time to look at the full picture ...

I'm not sure about that, it might have something to do with your gasLimit? Either way, I think that's more of an application specific bug, so I think I'll close this issue now.
