[SOLVED] Error WebHook by Trinsic API (former Streetcred)

Basic .net core web application throws error while receiving a POST-request (webhook) from TrinsicAPI.

ERROR:

Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException: Bad chunk size data.

The definition of the WebHook can be found here: https://docs.trinsic.id/docs/webhooks-1

And the WebHook-Receiver looks like this:

[DisableRequestSizeLimit]
        [HttpPost]
        public async Task<ActionResult> Post([FromBody] WHPayloadModel payload)
        {
            // Do cool stuff
            // dummy Async method
            var test = await _client.ListWebhooksAsync();
            return Ok();
        }
public class WHPayloadModel
    {
        public enum WHMessage_Type
        {
            [EnumMember]
            new_connection,
            [EnumMember]
            credential_request,
            [EnumMember]
            verification,
            [EnumMember]
            new_inbox_Message
        }

        [DataMember]
        public String Message_Type { get; set; }

        [JsonProperty(PropertyName = "object_id")]
        public String Object_id { get; set; }

        [JsonProperty(PropertyName = "data")]
        public Dictionary<String, String> Data { get; set; } = new Dictionary<String, String>();
    }

And even if I try to catch the request via dynamic object like this - it still throws the same error:

[HttpPost]
        public async Task<ActionResult> Post([FromBody] dynamic payload)
        {
            // Do cool stuff
            // dummy Async method
            var test = await _client.ListWebhooksAsync();
            return Ok();
        }

The error stays the same for different types of project Blazor project, or WebAPI.

The Post request works using Postman API tool. Therefore I did host the development application using the conveyor.cloud to access it from WAN.

This is the definition of the POSTMAN POST request

https://MyProjectName.conveyor.cloud/api/WebHook

Definition of the body:

    {
    "message_type": "new_connection",
    "object_id": "00000000",
    "data": {
        "param1": "value1",
        "param2": "value2"
    }
}

So the error seems to come directly from the trinsic API.

The trigger for the WebHook is when a new_connection is created.

Cheers!
