BREAKING CHANGE - Can't resolve some modules in 13.0.34

After rebuilding node_modules our app couldn't be build anymore. While building you get the following log output errors:

Module not found: Error: Can't resolve '@nativescript/core/data/observable-array' in '/Users/Shared/Entwicklung/xxx/nativescript-xxx-app/node_modules/@nativescript-community/ui-pager/angular/fesm2015'
Did you mean 'index.js'?
BREAKING CHANGE: The request '@nativescript/core/data/observable-array' failed to resolve only because it was resolved as fully specified
(probably because the origin is strict EcmaScript Module, e. g. a module with javascript mimetype, a '*.mjs' file, or a '*.js' file where the package.json contains '"type": "module"').
The extension in the request is mandatory for it to be fully specified.
Add the extension to the request.

The same error appears also for the packages:

• @nativescript/core/profiling

Because we had
"@nativescript-community/ui-pager": "^13.0.33"
the breaking changes were updated automatically.

We fixed the issue with specifing the previous version with:
"@nativescript-community/ui-pager": "13.0.33"

Let me know, if you need any more information.

Start by comparing the generated Angular fesm2015 output for versions 13.0.33 and 13.0.34, focusing on imports of @nativescript/core/data/observable-array and @nativescript/core/profiling. Reproduce the reported build with the newer version and confirm that the affected modules resolve without requiring the older pinned version.
