Asp.Net Core unit testing async controller

Hello i got this test:

[Fact]
    public async void Can_Paginate()
    {
        //fake data
        var product1 = new Product { ProductId = 1, ProductName = "P1" };
        var product2 = new Product { ProductId = 2, ProductName = "Product 2" };
        var product3 = new Product { ProductId = 3, ProductName = "Product 3" };
        var product4 = new Product { ProductId = 4, ProductName = "Product 4" };
        var product5 = new Product { ProductId = 5, ProductName = "Product 5" };
        var data = new List<Product>
        {
           product1,
           product2,
           product3,
           product4,
           product5
        }.ToAsyncEnumerable();

        var category1 = new Category { CategoryId = 1 };


        var prodCategoryData = new List<ProductCategory>
        {
            new ProductCategory { Product =product1,Category = category1},
            new ProductCategory { Product =product2,Category = category1},
            new ProductCategory { Product =product3,Category = category1},
            new ProductCategory { Product =product4,Category = category1},
            new ProductCategory { Product =product5,Category = category1}
        }.ToAsyncEnumerable();

        var dbSetMock = new Mock<DbSet<Product>>();
        //dbSetMock.As<IQueryable<Product>>().Setup(m => m.Provider).Returns(data.Provider);
        //dbSetMock.As<IQueryable<Product>>().Setup(m => m.Expression).Returns(data.Expression);
        //dbSetMock.As<IQueryable<Product>>().Setup(m => m.ElementType).Returns(data.ElementType);
        //dbSetMock.As<IQueryable<Product>>().Setup(m => m.GetEnumerator()).Returns(data.GetEnumerator());

        var pcDbSetMock = new Mock<DbSet<ProductCategory>>();
        // pcDbSetMock.As<IQueryable<ProductCategory>>().Setup(m => m.Provider).Returns(prodCategoryData.Provider);
        //pcDbSetMock.As<IQueryable<ProductCategory>>().Setup(m => m.Expression).Returns(prodCategoryData.Expression);
        //pcDbSetMock.As<IQueryable<ProductCategory>>().Setup(m => m.ElementType).Returns(prodCategoryData.ElementType);
        //pcDbSetMock.As<IQueryable<ProductCategory>>().Setup(m => m.GetEnumerator()).Returns(prodCategoryData.GetEnumerator());

        Mock<ApplicationDbContext> customDbContextMock = new Mock<ApplicationDbContext>();
        customDbContextMock.Setup(x => x.Products).Returns(dbSetMock.Object);
        customDbContextMock.Setup(x => x.ProductCategories).Returns(pcDbSetMock.Object);

        var loggerMock = new Mock<ILogger<ProductsController>>();
        var envMock = new Mock<IHostingEnvironment>();
        var httpContext = new Mock<HttpContext>().Object;
        var actionDescriptor = new Mock<Microsoft.AspNetCore.Mvc.Controllers.ControllerActionDescriptor>().Object;
        var modelState = new ModelStateDictionary();
        var actionContext = new ActionContext(httpContext, new Mock<RouteData>().Object, actionDescriptor, modelState);

        ProductsController controller = new ProductsController(customDbContextMock.Object, loggerMock.Object, envMock.Object);
        controller.pageSize = 3;
        controller.ControllerContext = new ControllerContext(actionContext);
        var result = await controller.List(1, 2);

My controller logic

 public async Task<IActionResult> List(int Id, int page = 1)
    {

        if (Id == 0)
        {
            ViewBag.CategoryName = "Wszystkie produkty";
            return View(await _context.ProductCategories.Include(c => c.Product).ToListAsync());
        }

        return View(await _context.ProductCategories
            .Include(p => p.Product)
            .Where(pt => pt.CategoryId == Id)
            .OrderBy(p=>p.ProductId)
            .Skip((page-1)*pageSize)
            .ToListAsync());
    }

My problem is that I Cannot mock_context.ProductCategories by using prodCategoryData and data lists as IAsyncEnumerable ,

when I cast them to Queryable I got this error instead :

Additional information: The source IQueryable doesn't implement IAsyncEnumerable. Only sources that implement IAsyncEnumerable can be used for Entity Framework .

Thanks.
