I'm currently struggling with CreatedAtRoute, below are the details.
Desired solution in the future
Return object and URI in location header linking to endpoint GetGlobalSettings.
Current situation and problem
I have the following POST endpoint for resource creation which returns CreatedAtRoute like this return CreatedAtRoute(nameof(GetGlobalSettings), result.Data);
The route set in the location header should link to the endpoint with this method head:
[HttpGet]
[ProducesResponseType(StatusCodes.Status200OK)]
[ProducesResponseType(StatusCodes.Status404NotFound)]
public async Task<ActionResult<GlobalSettingDto>> GetGlobalSettings()
With this I always get the following exception:
System.InvalidOperationException: No route matches the supplied values.

I have API-versioning active, so I also tried the CreatedAtRoute-call like this:
var routeValues = new { version = "1.0" };
return CreatedAtRoute(nameof(GetGlobalSettings), routeValues, result.Data);
But this still throws the same error.
