There is simple method returning Ok:

[HttpGet("request_name")]

public IActionResult request_name()

{

    using (var db = new WordContext())

    {

        return Ok("This is ok response string");

    }

}

And simple request in ngx:

request_name() {

    return this.http

        .get<string>(`${this.apiUrl}/request_name`);

    }.subscribe(x => {



    });

I can see code 200 "This is ok response string" in chrome, but there is error message in chrome console:

ERROR HttpErrorResponse {headers: HttpHeaders, status: 200,
statusText: "OK", url:
"http://localhost:4200/main/name/request_name", ok: false, …}

What does it mean and how do I solve it?

If your response type is not a JSON it will just pass the response to the error

Try something like this

request_name() {

    return this.http

        .get<string>(`${this.apiUrl}/request_name`, {responseType: 'text'});

    }.subscribe(x => {



    });

Whereas don't use subscribe use pipe operator and tap to read the response - hope i think you are using HttpClient in angular

    return this.http

            .get<string>(`${this.apiUrl}/request_name`, {responseType: 'text'});

        }.pipe(tap(res => {

           console.log(res);

        }));
