我的ASP.NET Core API未返回所有行

Question

My ASP.NET Core API is only returning the first two rows out of 40.

I have tried

services.AddMvc().AddJsonOptions(options => options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore);

It sent VS code in to an endless loop. Any ideas on where to look to fix this? I am using the browser and postman to consume the api with the same results.

[EnableCors]
[HttpGet]
public ActionResult<IEnumerable<Fuaxclient>> GetClient()
{
    return _context.clientList;
}

I am expecting to get proper json code of about 48 rows. Instead I'm getting 2 rows and broken json. I get this error from FireFox Web Console

error: null​
headers: Object { normalizedNames: Map(0), lazyUpdate: null, headers: Map(0) }
​message: "Http failure response for https://fuaxclientapi.azurewebsites.net/api/fuaxclient: 500 Internal Server Error"​
name: "HttpErrorResponse"
​ok: false
​status: 500
​statusText: "Internal Server Error"
​url: "https://fuaxclientapi.azurewebsites.net/api/fuaxclient"

The API is still running if you would like to try the API to see what I'm talking about. ​

Answer 1

Ok after much digging and researching and banging my head on the desk, I have found my issue. I had NULL in my database and the API stopped at the NULL.

Answer 2

status: 500
​statusText: "Internal Server Error"

As the error 500 itself suggests there error is on the server, in this case the url( endpoint api) stated as https://fuaxclientapi.azurewebsites.net/api/fuaxclient has issue.

It returns invalid json as validated here .

The return value need to be fixed in the api.
