Authentication Issue in Blazor Wasm

Question

Hello,
I configure the openid into blazor wasm with asp.net core webpi
I did configure the openid setting in program.cs of asp.net core webapi and webapi are secure.

but after login, webapi accessible. In blazor wasm, I have seen this issue and I cannot see who is logged in user
I also added AthenticationStateProvider but still not working.

Answer 1

the error indicates you did not config the wasm app settings:

I assume the OpenId code is looking for the client id, and authority:
