MemoryPackSerializationException: Length header size is larger than buffer size when serializing large collection of metrics

[proxusiiotplatform]

I'm experiencing an issue when trying to serialize/deserialize a collection of metrics data using MemoryPack with NATS.

When attempting to serialize and send a large collection of metrics via NATS, I'm getting this error:
"MemoryPack.MemoryPackSerializationException: Length header size is larger than buffer size, length: 33554432"

Code Example

[MemoryPackable]
public partial record ProxusActorMetrics {
    public string Device { get; set; }
    public long TotalRequests { get; set; }
    public long SuccessfulRequests { get; set; }
    // ... other metrics properties
}

// NATS Serializer
public sealed class NatsMemoryPackContextSerializer<T> : INatsSerializer<T> {
    public static readonly INatsSerializer<T> Default = new NatsMemoryPackContextSerializer<T>();

    public void Serialize(IBufferWriter<byte> bufferWriter, T value) {
        MemoryPackSerializer.Serialize(bufferWriter, value);
    }

    public T? Deserialize(in ReadOnlySequence<byte> buffer) =>
        MemoryPackSerializer.Deserialize<T>(buffer);
}

// Publishing code
var metricsCollection = new List<ProxusActorMetrics>();
// ... populate metrics
await fJs.PublishAsync("metrics.topic", metricsCollection, cancellationToken: fCts.Token);

Any update?

Thank you.
The phenomenon occurs when the ReadOnlySequence is less than the byte string to be deserialised.
It is difficult to tell whether this is a problem with NATS or MemoryPack.
If there is a code that can reproduce it easily, we can investigate it.
