Unknown object passed to sourceOfConfig() error

[experfy-ismetbibic]

Hello,
We're trying to incorporate ember-bootstrap addon in one of our engines, however we're running into some issues.
When starting the host app which has the engine mounted we're getting the following error:
unknown object passed to sourceOfConfig(). You can only pass back the configs you were given.

Seems like the issue is not on the ember-bootstrap side (ember-bootstrap/ember-bootstrap#1626) considering when downgrading the ember-engines version to 0.8.15 the error doesn't appear.

We're seeing this issue as well, but we're not using ember-bootstrap.

I had the same issue when I tried including a private ember addon in dependencies. Moving it to devDependencies made the error disappear (downgrading engines to 0.8.15 did not help).

I do have another issue, though, which is probably totally unrelated. Moving the addon to dependencies was a way of me trying to solve that other issue, that's when I bumped into this one.

Quick follow-up, the solution is definitely not moving things to devDependencies as mentioned in the linked issue.

Not sure where the issue lies but I saw that @embroider/macros was printing the error and I managed to get it working by:

• downgrading ember-engines to 0.8.15 as @experfy-ismetbibic suggested
• and also setting ember-basic-dropdown resolution to 3.0.19 (in our project it is included as a dependency of ember-power-select)

That way @embroider/macros resolved to 0.42.3 tops and things seem to work fine.
It also helped that I saw that in our private addon a full package reinstall (deleting lockfile) made this error appear, without any engine usage, so I suspect this is not related to ember-engines in the end.

I've got the same issue here but I cannot downgrade to @embroider/macros 0.42.3 as other dependencies requires upper versions...
I guess ember-engines needs to be updated to properly support new @embroider/macros versions?
Not sure if it is related but a breaking changes has been added on https://github.com/embroider-build/embroider/blob/7e5b1fe5398ed6b7ff81f4d65fabcbeac7b2930b/CHANGELOG.md#v0430-2021-07-13 ...

I fixed the issue by bumping ember-bootstrap and other dependencies to newer versions (and one downgrade). Definitely a @embroider/macros version mismatch issue between multiple dependencies ; but nothing specific to ember-engines to be fixed in practice indeed.
