Hi I am using ABP Framework with Angular, and I encountered the following error when running my application:
ERROR NullInjectorError: R3InjectorError(Standalone[_TenantsComponent])[InjectionToken undefined -> InjectionToken undefined -> InjectionToken undefined -> InjectionToken undefined]:

Context:
ABP V "@abp/ng.core": "~9.0.4",
Angular 19
I am working with ABP Angular UI.
_TenantsComponent is a standalone component. This error occurs when navigating to the Tenants Management page.
My Question Is:
What could be causing this error in ABP Angular?

Hello,
Thank you for your response. I did not create _TenantsComponent.ts myself; it comes as part of the ABP Framework. Could you guide
me on where I can locate it, or if there are any required configurations I might have missed?Additionally, I would like to know if this issue is related to missing providers or incorrect module imports.
The error occurs when I click on SaaS > Tenants in the application.

What could be causing this error in ABP Angular?
Hello, this problem occurs because of your angular version. That is to say, ABP version 9.0 supports Angular version 18. If you want to use Angular v19, you need to use the latest ABP version that is 9.1.
You can follow the release notes and migration guide to sustain version compatibility.
