cannot consume a scoped service from singleton

I am getting the above error and I realize why, but the odd behavior I see that it only happens in our Dev environment and not in for example our staging or Production environment and it is the exact same code. In the startup there is :

services.AddSingleton<ExcahngeService>();
services.AddScoped<ITradingService, TradingService>();

This throws the error: "cannot consume a scoped service from singleton"

but it only happens in a development environment and it is the same code in all environments

Could this be due to a timing issue, where the environment is slower ?

Scoped instance lifetime is limited, It is only available per request. So you are consuming an instance from Scoped service into Singleton and the error throws because of the scoped service is disposed. Either make both Singleton or Scoped
