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:

https://github.com/embroider-build/embroider/blob/a4b7bb22438539ce218665df148c7fe62874a176/package.json#L36

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 😆
