Dear Sir, I'm using asp.net zero for my below projects:
- Project have API Controller using .Netcore 2.2 (Backend)
- Project have Fontend using Angular 6 to call API in Project 1 (Frontend)
I add in devexpress report into my projects, and call the report from angular to .netcore project. However, there is an error message in .netcore logs file. Below is the error message:

Thanks maliming!
However, there is another error appear after amend as above.
In Angular, the error message showing "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:91/DXXRDV. (Reason: CORS header 'Access-Control-Allow-Origin' missing)", refer to below image:
While Asp.Net Core show error message "Castle.MicroKernel.ComponentNotFoundException: No component for supporting the service FlexiCloud.Web.Host.Controllers.CustomWebDocumentViewerController was found", please refer to attached logs file.

Make CustomWebDocumentViewerController inherit the ITransientDependency interface.

hi You can try to keep your original Cors settings unchanged, and add the default cors policy. That is, there are both the default CORS policy and Zero's default localhost policy.
You can refer to the documentation for a more detailed understanding of CORS. https://docs.microsoft.com/en-us/aspnet/core/security/cors
