The above dynamic import cannot be analyzed by Vite.

Which @angular/* package(s) are the source of the bug?

compiler-cli

Is this a regression?

Yes

Description

I upgraded to Angular 19.1 and activated HMR.
I am using the @angular/build:dev-server builder.
When I run "ng server" and as soon as I open my app, I get several warnings on the terminal console regarding Vite not able to analyze Dynamic imports.
I don't have dynamic imports, except for Lazy Loading components.
The warnings seem to be related to Lazy Loading and they disappear if I turn HMR off.

Please provide a link to a minimal reproduction of the bug

The above dynamic import cannot be analyzed by Vite.
See https://github.com/rollup/plugins/tree/master/packages/dynamic-import-vars#limitations for supported dynamic import formats. If this is intended to be left as-is, you can use the /* @vite-ignore */ comment inside the import() call to suppress this warning.
