So I have a simple requirement to gather logging data from a WASM client into a Web API.

NOTE we are not using Entity Framework...

I have created the following class:

public class EventInformation
{
public string Location;
public string Context;
public int Severity = 1;
}

With a simple web API target:

[Route("[controller]")]
[ApiController]
public class UserStateController : ControllerBase
{

[HttpPost]
[Route("LogEvent")]
[ProducesResponseType(StatusCodes.Status200OK)]
[ProducesResponseType(StatusCodes.Status400BadRequest)]
[ProducesResponseType(StatusCodes.Status500InternalServerError)]
public IActionResult LogEvent([FromBody] EventInformation logData)
{
string Context = logData.Context;
string Location = logData.Location;
int Severity = logData.Severity;
return Ok();
}
}

I run it with the swagger.. with this json payload

{
"Context": "hello",
"Location": "world",
"Severity": 0
}

and get...

Runs to the break point all looks good except where is the data? Doesn't seem t be populating my logData parameter from my JSON body?

Your model has fields which System.Text.Json does not support by default. If this is 3.1, consider switching to using properties. When using 5.0, you could consider using a SerializerOptions if you must use fields in your model: https://docs.microsoft.com/en-us/dotnet/standard/serialization/system-text-json-how-to?pivots=dotnet-5-0#include-fields
