Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0 while I build the project and upload it in server. about quant-ux

Hi,

If I understood correctly you are not using the vue dev server. You use npm run build and use the build artifacts on a Webserver (NGINX etc)?

In this case you need to configure a proxy. The UI will make request to /api/... These request need to be send to a Quant-UX server. One of them is You can first try with mine https://v1.quant-ux.com`. If you want a complete standalone installation, you need to install the backend as well.

Yes, you understand it correctly.
How can I install the backend?

Please have a look here: https://github.com/KlausSchaefers/qux-java

If you have issues installing let me know. It should be pretty strain forward.

1. Install Java 8

2. Install Mongo

3. Get mail server account

4. updater config file

5. Build fat jar with maven

6. run far jar

[SharifTanvir]

my vue.config.js file is

var path = require('path');
module.exports = {
  publicPath: '/',
  devServer: {
    proxy: {
      '^/rest': {
        target: 'https://v1.quant-ux.com',
        ws: true,
        changeOrigin: true
      },
      '^/examples': {
        target: 'https://v1.quant-ux.com',
        ws: true,
        changeOrigin: true
      }
    }
  },
  chainWebpack: config => {
    config.resolve.alias.set('src', path.resolve('src'))
    config.resolve.alias.set('assets', path.resolve('src/assets'))
    config.resolve.alias.set('components', path.resolve('src/components'))
    config.resolve.alias.set('dojo', path.resolve('src/dojo'))
    config.resolve.alias.set('common', path.resolve('src/common'))
    config.resolve.alias.set('vommond', path.resolve('src/vommond'))
    config.resolve.alias.set('views', path.resolve('src/views'))
    config.resolve.alias.set('canvas', path.resolve('src/canvas'))

    config.resolve.alias.set('core', path.resolve('src/core'))
    config.resolve.alias.set('dash', path.resolve('src/dash'))
    config.resolve.alias.set('public', path.resolve('src/public'))
    config.resolve.alias.set('services', path.resolve('src/services'))
    config.resolve.alias.set('nls', path.resolve('src/nls'))
    config.resolve.alias.set('themes', path.resolve('src/themes'))
    config.resolve.alias.set('export', path.resolve('src/export'))
    config.resolve.alias.set('examples', path.resolve('src/examples'))

    config.resolve.alias.set('player', path.resolve('src/player'))
    config.resolve.alias.set('style', path.resolve('src/style'))
  }
}

Still, I am getting the previous error while I am trying to run it on my server after the build.
I am getting this after hitting the API. and the API response is :

body: ReadableStream
bodyUsed: true
headers: Headers {}
ok: true
redirected: false
status: 200
statusText: "OK"
type: "basic"

In my browser's network option I am getting this image
