Attempting to upgrade Discourse on `tests-passed` [from commit 2ddabc3](https://github.com/discourse/discourse/compare/2ddabc3...tests-passed) failed with this error:
```plaintext
. Compiler said: Error: Assertion Failed: Using `{{controller}}` or any path based on it ('javascripts/explorer-query-result' @ L26:C65) has been removed in Ember 2.0
```
After that failed, we thought perhaps we need to upgrade all the plugins first based on [this post](https://meta.discourse.org/t/admin-statistics-report/50943/8).
We tried updating the discourse-solved plugin [from version 9936707](https://github.com/discourse/discourse-solved/compare/9936707...master) but got the same error.
Has anyone run into this before? Would doing a `./launcher rebuild app` solve this?

This looks like [data explorer](https://meta.discourse.org/t/32566?silent=true), I believe we recently fixed it

Yep! Looks like that was it… thanks!
After updating the data-explorer plugin (which succeeded), discourse and the other plugins are updating successfully as well.
