Cant query the data with specified uid

I got a problem, I am using aps.net 6.0 with ef and dbcontext, I tried to query the uid with 16 char string, however, its not working: I set dbcontext and its working and connected, its string queryuid(uid) { Dbconnection dbcon = dbContext.dbconnection.firstOrDefault(e=>e.Uid == uid); which dbcon always return null, however there are 3 records in database with uid I wanna find, the uid is 16 char string and when I change as: int count = dbContext.dbconnection.Count(e=>e.Uid == uid); its return the int of 2, which is correct, I even tried: dbContext.dbconnection.Where(e=>e.Uid == uid).first(); dbContext.dbconnection.Where(e=>e.Uid == uid).firstOrDefualt(); It's alwasy return null. Can I know whats wrong?

✅ iis problem

I have a question: in asp.net6.0 I handle the jwt unaothorized error in program.cs: // Adding Jwt Bearer .AddJwtBearer(options => { options.SaveToken = true; options.RequireHttpsMetadata = false; options.TokenValidationParameters = new TokenValidationParameters() { ValidateIssuer = true, ValidateAudience = true, ValidAudience = configuration["JWT:ValidAudience"], ValidIssuer = configuration["JWT:ValidIssuer"], IssuerSigningKey = new SymmetricSecurityKey(System.Text.Encoding.UTF8.GetBytes(configuration["JWT:Secret"])), ValidateIssuerSigningKey = true, }; options.Events = new JwtBearerEvents { OnChallenge = context => { context.HandleResponse(); context.Response.OnStarting(async () => { // Write to the response based on token expiration var token = context.Request.Headers["Authorization"].ToString().Replace("Bearer ", ""); if (IsTokenExpired(token)) { context.Response.StatusCode = StatusCodes.Status401Unauthorized; context.Response.ContentType = "application/json"; // Set the content type to JSON var response = new Response { Message = "Your token has expired.", Error = new Err { Type = "authorization", Content = "The provided token is no longer valid." }, }; await context.Response.WriteAsync(System.Text.Json.JsonSerializer.Serialize(response)); } }); return Task.CompletedTask; } }; }); But the code only works in localhost, not in iis, how I make it work in iis? Should I set somthing in iis?
