how to test minimal api controller with query parameters?

[ivanjx]

so i made a controller like this:
application.MapPost("/registration/verify", controller.Verify);
public async Task<IResult> Verify( [FromQuery(Name = "token")] string? token, CancellationToken cancellationToken)

and i test it like this with HttpClient from WebApplicationFactory<>:

HttpRequestMessage request = new()
        {
            Method = HttpMethod.Post,
            RequestUri = new Uri("/registration/verify?token=1122334455667789")
        };
var response = await client.SendAsync(request);

but it shows this instead:

System.Net.Http.HttpRequestException : Response status code does not indicate success: 404 (Not Found).
   at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode()

works fine if i dont include the ?token=... part. what am i doing wrong?
