deserializeMsgPack method throws exception while using with ASP.NET Core about msgpack.js HOT 6 CLOSED

Can you please also log the content of data and its type (typeof(data))? This doesn't look like a byte array which it's supposed to be.

from msgpack.js.

It is a complex object. But I tried with simple string, that also not working.

[HttpGet("{id}")]
public ActionResult<string> Get(int id)
{
    return "value";
}

Here is the response header.

from msgpack.js.

The thing is, the deserializeMsgPack function expects a byte array to be passed in. A byte array consists only of bytes. A byte is an integer value in the range of 0 to 255. All of these values are handled in the code. If something else occurs, then it's not a byte array. And chances are that it needs further conversion to be deserialisable.

I'll have to create a sample project and try out myself what's happening there. I can't make any more assumptions without investigating live code.

Here's code from where I use this library. It processes data received from a WebSocket client.

function onMessage(event) {
    let array = new Uint8Array(event.data);
    let obj = deserialize(array);
}

event.data is already a binary array and is then converted into a Uint8Array. Maybe you need to do something similar.

Okay. Let me try.

Any news here? I can't create a demo project because the type MessagePackOutputFormatter cannot be found anywhere. Can you maybe provide a minimal test case for this? I only know about ASP.NET Core 2.1, you seem to use 2.2. Maybe I'll have to wait a bit to run your example.

Oops, my bad. I am able to resolve it. Full details here - https://dotnetthoughts.net/using-message-pack-with-asp-net-core/. Thank you for your response 👍
