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.

Thank you for confirming your version details.
As mentioned earlier, ABP 9.0 is compatible with Angular 18. If you wish to leverage the features of Angular 19, you will need to upgrade your project to ABP 9.1.
In summary:
-
ABP 9.0 supports Angular 18
-
ABP 9.1 supports Angular 19
Please let me know if you need any further clarification. I appreciate your cooperation.

Thanks for your reply.I already updated the ABP CLI using the following command: .dotnet tool update -g Volo.Abp.Cli. After that, the backend AuthServer app did not start, and I encountered some other issues on the backend.
