[Solved] ASP.Net Core: There is no argument given that corresponds to the required parameter options

Hi,

I am trying to get data from DB and move them to list as shown below:

public JsonResult GetEvents()
{
    using (ApplicationDbContext dc = new ApplicationDbContext())
    {
        var events = dc.CalEvents.ToList();
        return new JsonResult(new { Data = events, JsonRequestBehavior = System.Web.Mvc.JsonRequestBehavior.AllowGet });
    }
}

but the following error comes up in the ApplicationDbContext

There is no argument given that corresponds to the required parameter 'options' of 'ApplicationDbContext.ApplicationDbContext(DbContextOptions<ApplicationDbContext>)'

using ExpenseTracker.Models;
using ExpenseTrackerApplication2023;
using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;

namespace ExpenseTracker.Data
{
    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
            : base(options)
        {
        }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);

            modelBuilder.Entity<ApplicationUser>()
                .Property(e => e.firstName)
                .HasMaxLength(250);

            modelBuilder.Entity<ApplicationUser>()
                .Property(e => e.lastName)
                .HasMaxLength(250);
        }

        public DbSet<Transaction> Transaction { get; set; }
        public DbSet<Category> Categories { get; set; }
        public DbSet<S3FileDetails> S3FileDetails { get; set;}
        public DbSet<CalEvents> CalEvents { get; set; }
    }
}
