Unable to find endpoints. Invalid URI

I have this code on my controller

c#
[Route("api/[controller]")]
[ApiController]
[Authorize(Roles = "Admin")]
public class AdminController : ControllerBase

c#
[Route("api/[controller]")]
[ApiController]
[Authorize(Roles = "Admin")]
public class AdminController : ControllerBase

In other projects https://localhost:<PORT>/api/Admin/... would return the data. But now the URI is invalid. As it is a .NET 8 project, I am unsure as to how to add swagger as well

Unable to Promote or Demote users

I have buttons to promote and demote user roles, however they are currently doing nothing.

c#
@if (user.IsAdmin)
{
    <button class="btn btn-danger" @onclick="() => DemoteUser(user.UserId)">Demote</button>
}
else
{
    <button class="btn btn-success" @onclick="() => PromoteUser(user.UserId)">Promote</button>
}
...

@code
{
  public List<UserInfo> Users { get; set; } = new ();
  
  protected override async Task OnInitializedAsync()
  {
      var users = await UserManager.Users.ToListAsync();
      foreach (var user in users)
      {
          var roles = await UserManager.GetRolesAsync(user);
          var userInfo = new UserInfo
          {
              UserId = user.Id,
              Email = user.Email,
              Roles = new List<string>(roles),
              IsAdmin = roles.Contains("Admin")
          };
          Users.Add(userInfo); 
      }
  }
  
  private async Task PromoteUser(string userId)
  {
      var user = await UserManager.FindByIdAsync(userId);
      await UserManager.AddToRoleAsync(user, "Admin");
      await OnInitializedAsync();
  }
  
  private async Task DemoteUser(string userId)
  {
      var user = await UserManager.FindByIdAsync(userId);
      await UserManager.RemoveFromRoleAsync(user, "Admin");
      await OnInitializedAsync();
  }
}

c#
@if (user.IsAdmin)
{
    <button class="btn btn-danger" @onclick="() => DemoteUser(user.UserId)">Demote</button>
}
else
{
    <button class="btn btn-success" @onclick="() => PromoteUser(user.UserId)">Promote</button>
}
...

@code
{
  public List<UserInfo> Users { get; set; } = new ();
  
  protected override async Task OnInitializedAsync()
  {
      var users = await UserManager.Users.ToListAsync();

          };

Authorised endpoint returns 401

I am trying to add authentication to my app. I followed a recent tutorial almost verbatim, however my code is not working. I have login and register endpoints that are working fine.

c#
//--------
AuthController.cs
...
private string CreateToken(User user)
    {
        List<Claim> claims = new()
        {
            new (ClaimTypes.Name, user.UserName),
            new (ClaimTypes.Role, "Admin")
        };
        
        SymmetricSecurityKey key = new(Encoding.UTF8.GetBytes(_configuration["JwtSettings:Key"]!));
        
        SigningCredentials creds = new(key, SecurityAlgorithms.HmacSha256Signature);
        
        JwtSecurityToken token = new(
            claims: claims,
            expires: DateTime.Now.AddDays(30),
            signingCredentials: creds
        );
        
        return new JwtSecurityTokenHandler().WriteToken(token);
    }
//--------
Program.cs
...
services.AddAuthentication().AddJwtBearer(options =>
{
    options.TokenValidationParameters = new TokenValidationParameters
    {
        ValidateIssuerSigningKey = true,
        ValidateAudience = false,
        ValidateIssuer = false,

        IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(config["JwtSettings:Key"]!))
    };
});
...
//-------
WeatherForecastController.cs
...
[HttpGet]
[Authorize(Roles = "Admin")]
public IEnumerable<WeatherForecast> Get() { ... }

c#

AuthController.cs

private string CreateToken(User user)
    {
        List<Claim> claims = new()
        {
            new (ClaimTypes.Name, user.UserName),
            new (ClaimTypes.Role, "Admin")
        };
        
        SymmetricSecurityKey key = new(Encoding.UTF8.GetBytes(_configuration["JwtSettings:Key"]!));
