[BUG]: Cannot serialize/deserialize byte arrays

[anthiras]

Library Version

6.0.3

.NET Runtime

.NET 10

OS and Architecture

macOS (Apple Silicon)

How to reproduce?

Run the snippet below which performs serialization and deserialization using the high level API with two sample classes. One class has a byte[] property and fails on serialization, the other has a ReadOnlyMemory<byte> property and fails on deserialization.

Failing test

Program.cs


using Parquet.Serialization;

ByteArrayEvent[] byteArrayEvents = [new() { ByteArray = [1, 2, 3] }];
ByteMemoryEvent[] byteMemoryEvents = [new() { ByteMemory = (ReadOnlyMemory<byte>) new byte[]{1, 2, 3} }];

Console.WriteLine("### Testing byte[] ###");
await TrySerializeDeserialize(byteArrayEvents);
Console.WriteLine("### Testing ReadOnlyMemory<byte> ###");
await TrySerializeDeserialize(byteMemoryEvents);

async Task TrySerializeDeserialize<T>(T[] data) where T : class, new()
{
    try
    {
        await ParquetSerializer.SerializeAsync(data, "data.parquet");
        await ParquetSerializer.DeserializeAsync<T>("data.parquet");
        Console.WriteLine("Success!");
    }
    catch (Exception e)
    {
        Console.WriteLine(e);
    }
}

public class ByteArrayEvent
{
    public byte[] ByteArray { get; set; } // can deserialize, cannot serialize
}

public class ByteMemoryEvent
{
    public ReadOnlyMemory<byte> ByteMemory { get; set; } // can serialize, cannot deserialize
}
