Having trouble fetching data from database for chart in ASP .NET Core

I have troubles with loading data from my Azure SQL database to a chart I'm creating using chartJS. I am trying to fetch data from columns "hrPlan", "hrSub" and "hrFact" for the year 2021 from the "workTS" table, but it is currently working incorrectly.
If I try to get values from hrPlan,hrSub or hrFact in a log directly from chart function like this: console.log("hrPlan=" + hrPlan); I'm getting the following error: Uncaught ReferenceError: hrPlan is not defined I think i didn't properly gave data values to my chart function, but I might be wrong.
Here's how it supposed to look like (all data is hardcoded): Here's how it looks now: dbo.workTS: My code for the workTS model:

public class WorkTS
    {
        public string? org { get; set; }
        public DateTime? dt { get; set; }
        public decimal? hrFact { get; set; }
        public decimal? hrPlan { get; set; }
        public decimal? hrReestr { get; set; }
        public DateTime? dtSynchro { get; set; }
        public DateTime? dtMonth { get; set; }
        public decimal? hrSub { get; set; }
        public decimal? hrFactWSub { get; set; }
    }

Context:

public class AzureDBContext : DbContext
    {
        public DbSet<WorkTS> WorkTs { get; set; }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.Entity<WorkTS>(builder =>
            {
                builder.HasNoKey();
                builder.ToTable("workTS");
            });
        }

        public AzureDBContext(DbContextOptions<AzureDBContext> options)
            : base(options)
        {            
        }
        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            optionsBuilder.UseSqlServer("{database connection string}");
        }
    }

Controller:

private readonly AzureDBContext _azdb;

        public HomeController(ILogger<HomeController> logger, AzureDBContext azcontext)
        {
            _logger = logger;
            _azdb = azcontext;
        }

        public async Task<ActionResult> OnGetWorkTSData_MTK()  
        {            
            var plan = _azdb.WorkTs.Where(w => w.org == "ООО \"МТК\"").Where(w => w.dtMonth.Value.Year == 2021).Select(w => w.hrPlan).ToArray();
            var sub = _azdb.WorkTs.Where(w => w.org == "ООО \"МТК\"").Where(w => w.dtMonth.Value.Year == 2021).Select(w => w.hrSub).ToArray();
            var fact = _azdb.WorkTs.Where(w => w.org == "ООО \"МТК\"").Where(w => w.dtMonth.Value.Year == 2021).Select(w => w.hrFact).ToArray();
            return new JsonResult(new { hrPlan = plan, hrSub = sub, hrFact = fact });
        } 

And finally, code for the chart:

            <div>
                <canvas id="workTSChart"></canvas>
            </div>
            <script>console.log("This is first debug line");</script>
            <script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
            <script>
                $(document).ready(function () {
                    $.ajax({
                        type: "Get",
                        url: '@Url.Action("OnGetWorkTSData_MTK","home")',
                        contentType: "application/json",
                        dataType: "json",
                        success: function (response) {                            
                            var data = response.hrPlan;
                            var data2 = response.hrSub;
                            var data3 = response.hrFact;
                                                        
                            var ctx = document.getElementById("workTSChart");
                            var workTSChart = new Chart(ctx, {
                                type: 'bar',
                                data: {
