loadComponents null

[antonybudianto]

Hi, I just upgraded to 1.0.0

and I got the following error:

Uncaught TypeError: Cannot read property 'then' of null
    at Object../src/index.js (index.js:13)
    at __webpack_require__ (bootstrap 9fe4b7230cd8077e37a9:707)
    at fn (bootstrap 9fe4b7230cd8077e37a9:112)
    at Object.0 (registerServiceWorker.js:117)

    at bundle.js:809

The offending line:

loadComponents().then(() => {

Please help, thank you

Having the same issue. I am guessing the tree traverse was not a success on server side. However, there was a change in the code that makes this fail ungracefully.
I think this line
if (!rootState.children) return null should not just return null but a promise.

I believe this is due to a change in this line

I am not entirely sure but i think that line changed from

var ids = window[_constants.COMPONENT_IDS] || [];
to
const state = window[LOADABLE_STATE]

notice the fallback here as []

There is a problem in the promise, this is why you are getting that error. I will fix it.

Thank you for the quick fix. much appreciated.

Anyway if you got this error, you should have a SSR issue. Do you have a __LOADABLE_STATE__ in your HTML code?

[kikoanis]

I do, but it always returns an empty array. I think because I use react-router and error boundary component. It seems that I can't get the tree traverse working correctly. Will do more digging and see if I notice anything in your code. Thanks again.

Not sure if this change was necessary
if (!state || !state.children)

You may not have a component that needs to be lazy loaded

I've __LOADABLE_STATE__ on the html, but still error

@neoziro , I think this line didn't check for empty object, the state is {} from my debug result
