Controller responds 200 but doesnt send any data in ASP.NET

I have a ASP.NET Core for frontend calling an ASP.NET API. The response of this api is comming as 200 in my frontend controller. When this same endpoint with the same parameters is tested it returns a JSON with an array of "pavimentos".
But in Ajax, data comes as "null" for this call

The Integration method returns the content from the response data

RaulinoOP•4/5/24, 6:06 PM

The request is made and status is 200

RaulinoOP•4/5/24, 6:06 PM

The API Call with same endpoint retrieves data

RaulinoOP•4/5/24, 6:07 PM

Data comes as undefined

RaulinoOP•4/5/24, 6:08 PM

Only to show that the response is 200

Your Ajax call seems off

Pobiega•4/5/24, 6:09 PM

data: {}data: {} indicates to me you are giving it an object

Pobiega•4/5/24, 6:10 PM

but thats a GET request. GET requests dont have payloads

Pobiega•4/5/24, 6:10 PM

so you must pass the id via the query string instead

RaulinoOP•4/5/24, 6:10 PM

Ajax is calling my Controller /Pavimento/ListarPavimentosDoBloco

Pobiega•4/5/24, 6:11 PM

yeah, which expects an intint argument

Pobiega•4/5/24, 6:11 PM

but since its a GET, that argument has to come from the querystring

Pobiega•4/5/24, 6:11 PM

so your request should be /Pavimento/ListarBlablablbla?idBloco=12312/Pavimento/ListarBlablablbla?idBloco=12312

Pobiega•4/5/24, 6:13 PM

... no

Pobiega•4/5/24, 6:13 PM

thats not helping

Pobiega•4/5/24, 6:13 PM

the problem is that you are trying to pass a payload to a GET request

Pobiega•4/5/24, 6:13 PM

that. does. not. work.

Pobiega•4/5/24, 6:14 PM

POST can take a payload (aka request body), but GET cant

Pobiega•4/5/24, 6:14 PM

for GET, arguments come from route parameters or querystring

RaulinoOP•4/5/24, 6:14 PM

I tested it without the call before, it is passed as queryString in this format

RaulinoOP•4/5/24, 6:14 PM

Without the api call*

RaulinoOP•4/5/24, 6:14 PM

only calling the controller and returning the Id

Pobiega•4/5/24, 6:15 PM

I don't know the internals of the AjaxAjax method

Pobiega•4/5/24, 6:15 PM

but I'd look in your browser network log for that call

Pobiega•4/5/24, 6:15 PM

and verify that its passing a querystring for idBlocoidBloco

Pobiega•4/5/24, 6:15 PM

and not with the string variant

Pobiega•4/5/24, 6:15 PM

the intint isnt the problem :p

Pobiega•4/5/24, 6:18 PM

Im guessing that data: {}data: {} tries to send it as a request body, but you cant do that for GET so it just skips it. That makes the idBlocoidBloco default to 0, and thats why you get no results

RaulinoOP•4/5/24, 6:19 PM

Pobiega•4/5/24, 6:19 PM

thats not the network inspector

RaulinoOP•4/5/24, 6:19 PM

If I dont make the API call it display data as the object I creat

Pobiega•4/5/24, 6:19 PM

that screenshot doesnt show me anything of value tbh

RaulinoOP•4/5/24, 6:20 PM

including the "idBloco", being received in the params of ListarPavimentosDoBloco and being rendered

RaulinoOP•4/5/24, 6:20 PM

Its is being passed to the function... in the data object

Pobiega•4/5/24, 6:20 PM

a much simpler way to verify that would be with just setting a breakpoint and using the debugger, no?

Pobiega•4/5/24, 6:20 PM

or the network inspector

RaulinoOP•4/5/24, 6:21 PM

Dude yeah, but I will be honest with you... I dont know where this info is being logged! the debbuger is empty

RaulinoOP•4/5/24, 6:21 PM

I'm a Visual Studio Code User, VS is so different!!

Pobiega•4/5/24, 6:21 PM

but okay, if the value is passed, then you dont really have any issues here - its just a case of checking why your your method isnt working

RaulinoOP•4/5/24, 6:22 PM

RaulinoOP•4/5/24, 6:22 PM

Pobiega•4/5/24, 6:23 PM

¯\_(ツ)_/¯

Pobiega•4/5/24, 6:23 PM

I see Refit. Thats a rest api client generator thingy, right?

RaulinoOP•4/5/24, 6:24 PM

yes

Pobiega•4/5/24, 6:24 PM

yeah, no clue how to debug the internals of that

RaulinoOP•4/5/24, 6:24 PM

Program.cs

PPobiega yeah, no clue how to debug the internals of that

RaulinoOP•4/5/24, 6:25 PM

Idk what I do kakkaka

Pobiega•4/5/24, 6:25 PM
