好的，我们更加确定这里存在问题……因为堆栈跟踪中提到了 mergeMixins

Issue with `mergeMixins` when accessing a service in a getter

opened 06:29PM - 03 Apr 20 UTC

Recently found an issue with mergeMixins. it affects Ember versions at least as …far back as 3.12 and also current release and LTS. As I understand it, the issue is when a mixin defines a property (doesn’t necessarily have a value) then we try to access the value during construction before owner is set. This breaks getters that access services. Shared findings with @pzuraq. Error message: `Attempting to lookup an injected property on an object without a container, ensure that the object was instantiated via a container. Error: Assertion Failed: Attempting to lookup an injected property on an object without a container, ensure that the object was instantiated via a container.` [Code where issue arrises ](https://github.com/emberjs/ember.js/blob/v3.17.3/packages/@ember/-internals/metal/lib/mixin.ts#L475) (Please note: the original link was to `master` 😞. I've changed the tag to the version of ember published the day before, but I have no memory of the original code it linked to) [Reproduction](https://ember-twiddle.com/3147343e2dbf0e4c6965a50fa7e7389d?openFiles=controllers.application%5C.js%2C) ([Gist](https://gist.github.com/nlfurniss/3147343e2dbf0e4c6965a50fa7e7389d))
