Dear members,

i use a docker container based on the node:8 image to create a test instance of dspace 7 and the angular app.  I start Angular with the call

yarn start:dev

When I login with the UI I get the following error message

Cannot read property 'authenticated' of undefined

With every call of the UI yarn gives the following error

Error: The server returned an invalid object

The configuration file of the angular app

module.exports = {
  // Angular Universal server settings.
  ui: {
    ssl: false,
    host: '',
    port: 3000,
    // NOTE: Space is capitalized because 'namespace' is a reserved string in TypeScript
    nameSpace: '/'
  // The REST API server settings.
  rest: {
    ssl: false,
    host: 'localhost',
    port: 8080,
    // NOTE: Space is capitalized because 'namespace' is a reserved string in TypeScript
    nameSpace: '/spring-rest/api'

I would be grateful if you could tell me what caused the error.
