Sorry, this is a gotcha at the moment. We currently depend on a newer version of fastboot than any released version of ember-cli-fastboot uses.

If you’re using yarn you can use selective dependency resolution to get the newer fastboot directly like this:

embroider/package.json

Line 36 in a4b7bb2

"**/fastboot": "^3.1.0"

Perfect! I wasn't sure if it was something we were doing incorrectly :) you can close this issue if you'd like.

I'll leave this issue open until there's a release so other people are more likely to find it.

Thanks for a temporary solution @ef4, and in case someone uses workspaces like me, you got to add this in the workspace package.json's resolutions key. I kept trying within my ember app and it never worked 😆

https://github.com/GavinJoyce/embroider-spike/pull/19 @abhilashlr here is a working example of embroider and fastboot

FYI: there is a 3.0.0-beta.2 release meanwhile that comes with the latest fastboot dependency, and it fixed this issue here for me!

However it still doesn't work quite yet for me, now running into #160 it seems. Will comment over there...
