Unable to resolve service for type 'Microsoft.Extensions.FileProviders.IFileProvider' while attempting to activate my controller

Question

I have this in my controller

using Microsoft.Extensions.FileProviders;

[ApiController]
[Route("api/[controller]")]

public class PlanningController: ControllerBase
{
 private readonly IFileProvider fileProvider;

 public PlanningController(IFileProvider fileProvider)
 {
  this.fileProvider = fileProvider;
 }

[HttpGet]
[Route("GetTest")]
public async Task<IActionResult> GetTest()
{
  return NotFound();
}

When I call to getTest I get this error

An unhandled exception occurred while processing the request. InvalidOperationException: Unable to resolve service for type 'Microsoft.Extensions.FileProviders.IFileProvider' while attempting to activate 'api.Controllers.PlanningController'. Microsoft.Extensions.DependencyInjection.ActivatorUtilities.GetService(IServiceProvider sp, Type type, Type requiredBy, bool isDefaultParameterRequired)

I'm using ASP.NET Core 3.1

Any idea, please?

Thanks

Solved

I have added this in Startup.cs to inject in my controller

IFileProvider physicalProvider = new PhysicalFileProvider(Directory.GetCurrentDirectory());
services.AddSingleton<IFileProvider>(physicalProvider);

Thanks
