TypeError 'map' of null

[markgoho]

Getting this in the console on first page load:

Error: Uncaught (in promise): TypeError: Cannot read property 'map' of null
TypeError: Cannot read property 'map' of null
at new ConfigService (http://localhost:4200/vendor.bundle.js:26138:30)
at wpConfigFactory (http://localhost:4200/vendor.bundle.js:96289:12)

I'm initializing the module exactly how the docs state:
WordPressModule.forRoot('https://www.gideonlabs.com/', null, true),

[markgoho]

WordPressModule.forRoot('https://www.gideonlabs.com/'),

This gives the same TypeError message, so it must not be due to how I'm initializing the Module.

Using photonOptions() as instructed in the docs removes the error:

export function photonOptions() {
  return [
    { 'key': 'large', 'value': { w: 800, h: 360 } },
    { 'key': 'cropped', 'value': { crop: "160px,25,1400px,60" } },
    { 'key': 'resized', 'value': { resize: "400,220" } }
  ]
}

WordPressModule.forRoot('https://www.gideonlabs.com/', photonOptions(), true),

No error when doing it this way.
