Hi, I’ve been encountering an issue while trying to rebuild my Discourse instance, and I could use some assistance in resolving it. The error message I’m encountering during the rebuild process is as follows: Build Error (broccoli-persistent-filter:Babel > [Babel: @ember/test-helpers]) in @ember/test-helpers/-internal/build-registry.js [BABEL]: --- PLACEHOLDER PACKAGE --- This @babel/plugin-proposal-private-property-in-object version is not meant to be imported.

I’ve tried troubleshooting this issue on my own, but I’m unsure about the specific component or configuration causing this problem. Moreover, I have commented out all plugins to ensure that they are not the cause of the problem. Any insights or recommendations would be greatly appreciated.

Failed upgrade v3.0.6

It turns out this problem exists in versions v3.0.x.
I had to upgrade to v3.1.x, and the rebuild is succeeding now.
