Cannot read property 'map' of undefined?

hey man, thanks for writing this adapter!

i'm kind of new to aor and feathers, so it's entirely possible i'm just being a dunce, but i have this setup and i'm getting the above error in the browser when trying to do a simple list.

here are some relevant snippets:

• feathers-client.js

  
  import feathers from 'feathers-client'

const host = 'http://localhost:3000'

export default feathers() .configure(feathers.hooks()) .configure(feathers.rest(host).fetch(window.fetch.bind(window)))

- `app.js`

import React from 'react' import ErrorIcon from 'material-ui/svg-icons/alert/error' import {Admin, Resource} from 'admin-on-rest' import {restClient} from 'aor-feathers-client' import feathersClient from './feathers-client' import {AlertList} from './alerts' import Dashboard from './dashboard'

const options = {id: '_id'}

const App = () => <Admin dashboard={Dashboard} restClient={restClient(feathersClient, options)}>

export default App

- `alerts.js`

import React from 'react' import {List, Datagrid, TextField} from 'admin-on-rest'

// eslint-disable-next-line import/prefer-default-export export const AlertList = props => <List title="All alerts" {...props}>

- sample call to `http://localhost:3000/alerts` from browser

- some chrome debug output (i manually placed a `console.log` statement in aor saga code)

> i'm not using any authentication yet, which is diff from examples given, wonder if that might be an issue, or not relevent

any troubleshooting suggestions appreciated!

best,
tony.

doh! after some shut-eye noticed this on the server side:

  app:index "SequelizeBaseError: Unknown column 'Alert._id' in 'order clause'\n    at Query.formatError (/Users/tony/git/udx-api/node_modules/sequelize/lib/dialects/mysql/query.js:222:16)\n    at Query.connection.query [as onResult] (/Users/tony/git/udx-api/node_modules/sequelize/lib/dialects/mysql/query.js:55:23)\n    at Query.Command.execute (/Users/tony/git/udx-api/node_modules/mysql2/lib/commands/command.js:31:12)\n    at Connection.handlePacket (/Users/tony/git/udx-api/node_modules/mysql2/lib/connection.js:417:28)\n    at PacketParser.onPacket (/Users/tony/git/udx-api/node_modules/mysql2/lib/connection.js:93:16)\n    at PacketParser.executeStart (/Users/tony/git/udx-api/node_modules/mysql2/lib/packet_parser.js:73:14)\n    at Socket.<anonymous> (/Users/tony/git/udx-api/node_modules/mysql2/lib/connection.js:101:29)\n    at emitOne (events.js:115:13)\n    at Socket.emit (events.js:210:7)\n    at addChunk (_stream_readable.js:252:12)\n    at readableAddChunk (_stream_readable.js:239:11)\n    at Socket.Readable.push (_stream_readable.js:197:10)\n    at TCP.onread (net.js:589:20)" +1ms

used this for app.js:

import React from 'react'
import ErrorIcon from 'material-ui/svg-icons/alert/error'
import {Admin, Resource} from 'admin-on-rest'
import {restClient} from 'aor-feathers-client'
import feathersClient from './feathers-client'
import {AlertList} from './alerts'
import Dashboard from './dashboard'

// const options = {id: '_id'}

const App = () =>
  <Admin dashboard={Dashboard} restClient={restClient(feathersClient)}>
    <Resource name="alerts" list={AlertList} icon={ErrorIcon} />
  </Admin>

export default App

and voila:

so all good 👍 thanks again for the adapter 🙏
