Keyed service dependency problem when injecting in Program.cs

Question

I wrote a interface and implemented it in 3 services, but when I used AddKeyedScoped to inject these to project I get the following error.

Unhandled exception. System.InvalidOperationException: This service descriptor is keyed. Your service provider may not support keyed services.

Code:

services.AddKeyedScoped<IEPaymentService, SamanService>(BackofficeOptions.SamanBankService);
services.AddKeyedScoped<IEPaymentService, MellatService>(BackofficeOptions.MellatBankService);
services.AddKeyedScoped<IEPaymentService, MelliService>(BackofficeOptions.MelliBankService);
