ASP .NET Core Endpoint returns different Content Types

While testing my endpoints I recognized that an endpoint returned different Content Types when sending different input values. For instance: The endpoint returns a Supplier when an ID is given. If the HTTP Status Code is 200 the content type is "application/json; charset=utf-8; v=1.0". But when I submit bullshit like a random string instead of an integer, obviously the api returns a HTTP 400. The content type now is "application/json; charset=utf-8". The "v=1.0" is missing. It seems trivial but our integration tests check if the Content Type is like the expected application/json; charset=utf-8; v=1.0.

Also, we defined in the Startup.cs: options.DefaultApiVersion = new ApiVersion(1, 0);

Endpoint code:

[HttpGet("{id:int}")]
public async Task<IActionResult> GetById(int id)
{
    var body = await _lieferantenService.GetById(id);
    return Ok(body);
}

Does anybody encountered this kind of problem?

It is most likely that the response comes from a middleware and not from your code.

I think the middleware that validates input or the one that is responsible for model bindings. (Mapping bullshit to integer).

To customize the Response use InvalidModelStateResponseFactory of ApiBehaviorOptions.
