我有一个 Web API 项目，通过它注册并登录。在授权期间，我应该获取令牌，但出现错误： An unhandled exception has occurred while executing the request.

using System.Security.Cryptography;

namespace ASFT.Auth.Services
{
    public class TokenService : ITokenService
    {
        public string GenerateAccessToken(IEnumerable<Claim> claims)
        {
            var signinCredentials = new SigningCredentials(AuthOptions.Key, SecurityAlgorithms.HmacSha256);

            var tokenOptions = new JwtSecurityToken(
                issuer: AuthOptions.Issuer,
                audience: AuthOptions.Audience,
                claims: claims,
                expires: DateTime.Now.AddHours(48),
                signingCredentials: signinCredentials); …
