A suitable constructor for type 'ApplicationInventory.Services.ServerInventoryService' could not be located

问题

I am trying to create a service that is accessible by both Controllers and regular functions for all API calls to a specific endpoint for my ASP.Net Core 2.2 application. Whenever I try and inject the HttpClient class an error occurs before the functions can be reached/

I have setup my startup.cs as shown in documentation and have reduced the constructor inputs to just HttpClient so I know that's where the root of the issue is. I have added the HttpClient to the configure services section fo the Startup.cs class every way I can think of.

Startup.cs

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddCors();
            ...
                        // adding ability to make basic http calls 
            services.AddHttpClient<IServerInventoryService, ServerInventoryService>(c =>
            {
                c.BaseAddress = new Uri("https://serverinventory.cooperatorsgroup.ca/api/");
            }).ConfigurePrimaryHttpMessageHandler(() =>
            {
                return new HttpClientHandler()
                {
                    AllowAutoRedirect = false,
                    UseDefaultCredentials = true
                };
            });

}

Controller:

       private ILogger<ServerInventoryApiController> logger;
        private IHttpClientFactory clientFactory;
        private readonly IServerInventoryService ServerInventoryService;
        public ServerInventoryApiController(ILogger<ServerInventoryApiController> _logger, IServerInventoryService _service, IHttpClientFactory httpClientFactory)
        {
            ServerInventoryService = _service;
            logger = _logger;
            clientFactory = httpClientFactory;
        }

APIService:

  public class ServerInventoryService : IServerInventoryService
    {
        private HttpClient client;
        //        private readonly IConfiguration configuration;

        public ServerInventoryService(HttpClient httpClient)
        {
            client = httpClient;
        }

Everytime a call is made to the Service result is:

"InvalidOperationException: A suitable constructor for type 'ApplicationInventory.Services.ServerInventoryService' could not be located. Ensure the type is concrete and services are registered for all parameters of a public constructor."
