Asp.Net Core & Sqlite connection string in appsettings.json - cannot open database

I'm testing Hangfire in Asp.net Core 3.1 app. I want to persist data to sqlite database. I added connection string into appsettings.json file

"ConnectionStrings": {
"Default": "Data Source=C:\\database\\hangfireDb.db; Version = 3; New = True; Compress = True;"},

Here is Startup class

 public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
        
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllersWithViews();


        services.AddHangfire(configuration => configuration
                     .UseSimpleAssemblyNameTypeSerializer()
                     .UseRecommendedSerializerSettings()
                     .UseSQLiteStorage(Configuration.GetConnectionString("Default")));

    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }
        app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseRouting();

        app.UseAuthorization();

        app.UseHangfireServer();
        app.UseHangfireDashboard();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller=Home}/{action=Index}/{id?}");
        });
    }
}

Connection to database cannot be established

SQLite.SQLiteException: 'Could not open database file: Data Source=C:\database\hangfireDb.db; Version = 3; New = True; Compress = True; (CannotOpen)'

I can open database if I use only a path to database

services.AddHangfire(configuration => configuration
                     .UseSimpleAssemblyNameTypeSerializer()
                     .UseRecommendedSerializerSettings()
                     .UseSQLiteStorage("C:\\database\\hangfireDb.db"));

Or

"ConnectionStrings": {
"Default": "C:\\database\\hangfireDb.db"},

This does not look like a proper connection string. I think I'm missing something. Connection string should include "Data Source" and any additional tag, but in this case only path to database works.
