Telerik Report viewer not working when combined with Asp.net core in Asp .net Boilerplate

Reports in Telerik report viewer don’t display with Asp.net core framework in Asp.net boilerplate.

I have searched about it a lot. Check this.

(https://www.telerik.com/forums/asp-net-core-2-issue-with-reporting-r1-2019-and-antiforgery-token)

• Your Abp package version : 4.6.0
• Your base framework: Asp.net core 2.0 with Multipage web application (.net core 2.2 , .net framework 4.6.1)
• Exception : Invalid Client Id
• Steps needed to reproduce the problem :

1. Select ABP solution with .Net core 2.0 and Multipage web application.
2. Now try to Add Telerik report viewer and show data for Customer table.
3. It will give you invalid client id error in console and wont display data in report viewer.

This thing will work if we create a separate solution for rest apis. It also works if use Asp.net mvc framework instead of Asp.net core.

@kfrancis according to error message [IgnoreAntiforgeryToken] must be used. If you find a way to add custom headers to Teleriks requet for getting report data, you can use abp.security.antiForgery.getToken() on JavaScript side to get value of AntiForgery token and add it to request headers.

@ryancyq This is the only console error we get “Uncaught (in promise) Invalid ClientId” We don’t get any stack trace in VS. I can upload the solution to GitHub if you would like to check.
