Optional body parameters no longer work since upgrading to .NET Core 2.0 #6920
Description
I have an action filter that automatically checks ModelState and returns 400 if it's not valid.
We have a few actions that have optional body parameters, for example:
// POST api/values
[HttpPost]
public IActionResult Post([FromBody]SomeClass request = null)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
return Ok();
}
Specifying the default value of null used to be enough to mark them as optional. Since upgrading to ASP.NET Core 2.0 I get the following response:
{
"": [
"A non-empty request body is required."
]
}
