Describe the bug/Repro steps
Consider the following sample service that returns a collection of open entities

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.OData;
using Microsoft.AspNetCore.OData.Query;
using Microsoft.AspNetCore.OData.Routing.Controllers;
using Microsoft.OData.ModelBuilder;

var builder = WebApplication.CreateBuilder(args);

var modelBuilder = new ODataConventionModelBuilder();
modelBuilder.EntitySet<BasicType>("BasicTypes");

builder.Services.AddControllers().AddOData(
    options => options.EnableQueryFeatures().AddRouteComponents(
        modelBuilder.GetEdmModel()));

var app = builder.Build();

app.UseRouting();
app.MapControllers();

app.Run();

public class BasicType
{
    public int Id { get; set; }
    public Dictionary<string, object> DynamicProperties { get; set; }
}

public class BasicTypesController : ODataController
{
    [EnableQuery]
    public ActionResult<IEnumerable<BasicType>> Get()
    {
        return new List<BasicType>()
        {
            new BasicType
            {
                Id = 1,
                DynamicProperties = new Dictionary<string, object>
                {
                    { "DynamicInt32Property", 5 },
                    { "DynamicByteProperty", (byte)7 },
                    { "DynamicSByteProperty", (sbyte)11 },
                    { "DynamicInt16Property", (short)13 }
                }

3. The following requests containing dynamic properties of types Edm.Byte, Edm.SByte, and Edm.Int16 where a cast is applied to the left operand return empty results:

   • http://localhost:5043/BasicTypes?$filter=cast(DynamicByteProperty,Edm.Int32) eq 7
   • http://localhost:5043/BasicTypes?$filter=cast(DynamicSByteProperty,Edm.Int32) eq 11

4. The following requests containing dynamic properties of types Edm.Byte, Edm.SByte, and Edm.Int16 where a cast is applied to the right operand cause exceptions to be thrown:

Expected behavior
I expect to be able to successfully apply filter expressions referencing dynamic properties of type Edm.Byte, Edm.SByte, and Edm.Int16.

Additional context
This issue affect decimal dynamic properties too. However, for decimal dynamic properties, apply the m/M suffix to the value (right operand) seems to work as a workaround:

• http://localhost:5043/BasicTypes?$filter=DynamicDecimalProperty eq 7654321m

Do you try the declared property using byte? ==> Confirmed, it works.

http://localhost:5043/BasicTypes?$filter=DynamicByteProperty eq ABigNumberHere ==> ?
