Auth0 SPA+.net8

[ytkowshik_auth0]

Ready to post? First, try searching for your answer.
I am using auth0 react SDK and following the React+.net.

I am using .net 8 and dependency injection to add authentication. All my code is similar to the one in SDK quickstart but I am unable to get the application working. I deployed frontend and backend on the same port. Added cross origins inside the server.

I am using organisation auth0 tenant.

builder.Services.AddAuthentication(options =>
{
    options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
    options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
    options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme;

}).AddJwtBearer(o =>
{
    //Auth0
    o.Authority = jwtAuth.Issuer;//Domain
    o.RequireHttpsMetadata = false;
    o.TokenValidationParameters = new TokenValidationParameters
    {
        ValidateAudience = false,
        ValidateIssuerSigningKey = true
    };
    o.Events = new JwtBearerEvents()
    {
        OnAuthenticationFailed = c =>
        {
            string logFilePath = "log.txt";

            // Create a StreamWriter to write logs to a text file
            using (StreamWriter writer = new StreamWriter(logFilePath, append: true))
            {
                writer.WriteLine(c.Exception.ToString());
                writer.WriteLine(c.Options.Audience);
                writer.WriteLine(c.Options.Authority);
                writer.WriteLine(c.Options.TokenValidationParameters.AuthenticationType);
                writer.WriteLine(c.Options.ClaimsIssuer);
                // Add more log entries as needed
            }
            Console.WriteLine(c.Exception.ToString());
            return Task.CompletedTask;
        }
    };
});

I am getting two errors for the same.

1. IDX14100: JWT is not well formed, there are no dots (.)
2. IDX10609: Decryption failed. No Keys tried:

Please help.

Audience parameter is mandatory while sending these requests from frontend. It works after adding the audience.
