Hmm... Have I done something wrong? It throws an exception:

using Magic.IndexedDb;
using Magic.IndexedDb.Helpers;
using Microsoft.AspNetCore.Components;
using System.Text.Json;

namespace E2eTestWebApp.TestPages;

[Route("/WhereTest")]
public class WhereTestPage(IMagicDbFactory magic) : TestPageBase
{
    [MagicTable("Records", null)]
    private class Record
    {
        [MagicPrimaryKey("Id")]
        public int Id { get; set; }

        public int Int32Field { get; set; }
    }

    public async Task<string> Where1()
    {
        var database = await magic.OpenAsync(new DbStore()
        {
            Name = "Where.Where1",
            Version = 1,
            StoreSchemas = [SchemaHelper.GetStoreSchema(typeof(Record))]
        });
        await database.AddAsync<Record, int>(new Record()
        {
            Id = 1,
            Int32Field = 1
        });
        await database.AddAsync<Record, int>(new Record()
        {
            Id = 2,
            Int32Field = 2
        });
        await database.AddAsync<Record, int>(new Record()
        {
            Id = 3,
            Int32Field = 3
        });
        var result = await database
            .Where<Record>(x => x.Int32Field < 2)
            .ToListAsync();
        return JsonSerializer.Serialize(result.Select(x => x.Id));
    }
}

By the way, the steps to debug the test in visual studio:

1. run E2eTestWebApp in debug mode (not E2eTest)
2. in any browser, open http://localhost:XXXX/WhereTest
3. enter Where1 in the left input
4. press the left button, and WhereTestPage.Where1 will be executed

(Note the database deletion for unit test is done in E2eTest. When running E2eTestWebApp, it won't be automatically deleted, and primary key conflicts may occur.)

However in this case the debugger does not break at the exception... I don't why...

By the way, it seems that we are regarding exceptions/errors from JavaScript as a normal result.
