Nullability of reference types in return type of 'Task<ProviderConfiguration> InMemoryProviderConfigurationRepository.GetConfigurationSettingsAsync(string name, CancellationToken cancellationToken = default(CancellationToken))' doesn't match implicitly implemented member 'Task<ProviderConfiguration?> IProviderConfigurationRepository.GetConfigurationSettingsAsync(string name, CancellationToken cancellationToken = default(CancellationToken))'.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.

Cannot convert null literal to non-nullable reference type.

Non-nullable property 'id' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'login' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'display_name' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'type' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'broadcaster_type' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.
