Hi, this ticket can be closed. I was using temporarily using an angular.json file to run a migration which was overriding my project.json file containing the abp imports. Once it was deleted, it started working.
Yes, this is present. We have an equivalent project.json (due to using NX) file which contains this. I have replaced this file (abp.js) and all other files in the assets folder with the most up-to-date versions after running into this issue.
This is not a project I can share. And it's not easy to create a simple repro.
I am happy to provide files or snippets to work out what the issue is.
