SPFx application customizer no longer works on modern Site Contents page

[MartinLaplante]

Existing SPFx application customizer has stopped running on modern Site Contents page. Using F12 dev tools breakpoints, it seems that onInit() no longer fires on modern Site Contents page. Console shows this:

The application customizer runs correctly on other pages, including library and list view pages. This has been tested with Chrome and Edge on three different tenants, and started failing in the past few days. That error message is not there on the pages that work correctly, but they don't seem to load sitehubwebpack.js at all, whatever that is.

I'm also facing the same issue in application customizer in site contents page. In other pages it works fine but in site contents onInit is not invoking.

The issue has been addressed and will be rolling out in the next couple of weeks.

Hi, is there any fix that can be locally applied for existing Application Customizer projects?

[AJIXuMuK]

@BhargavPrasadGorakanti - no, you just need to wait until new service build is rolled out.

[AJIXuMuK]

Should be rolled out globally by now
