Glimmer 2 + Fastboot render issue

bakerac4 commented 7 years ago

I just upgraded an app that uses liquid-fire to glimmer 2. When trying to go directly to a page in Fastboot it gives me an error of

There was an error running your app in fastboot. More info about the error:

After playing around with it for awhile, it seems that the liquid outlets in my app are causing the error. I created a test repo that illustrates the issue https://github.com/bakerac4/fastboot-glimmer2-liquidfire-issue

To reproduce, just use ember fastboot --serve-assets and go to /sites/posts/1 via the url bar.

If you replace the liquid-outlet with a normal outlet there is no error and the page renders as expected.

I can also confirm that everything was fine on ember 2.8.

I'm also experiencing the same error. Downgrading to ember 2.8 solved the issue for now.

I am getting a similar error. I don't think it's fastboot-related. Same thing happens when I just use 'ember serve'. When I change {{liquid-outlet}} to just {{outlet}} everything works fine.

Any progress on this? I just ran into the same issue, even though we arent using liquid fire, so im curious what the solution might be

ef4 commented 7 years ago

@linearza if you aren't using liquid-fire, this is almost certainly a glimmer bug. Please file an issue on https://github.com/emberjs/ember.js

linearza commented 7 years ago

@ef4 - im sure it is! and i might do so, its just a rather complex error to recreate, so was just curious if anyone has solved it before perhaps. thanks though

This happens in my apps too if loading routes are present (works fine without loading routes).

Duder-onomy commented 6 years ago

This might still be an issue, running into it right now. Though, I have no liquid-outlets.
