«java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 2 column 1 path $» Kot-CodePudding

Hello i am trying to invoke a web service (using Retrofit) made by myself, with Slim4, however it is giving me the same error. I already went back and forth and tried many solutions i found on other threads however none of it worked yet .

This is my endpoint to do a get with Slim 4 and NOTORM library

$app->get('/api/anuncios', function ($request, $response) {
    require_once('db/dbconnection.php');
    foreach($db->anuncios()
    
            as $row){
                $data[] = $row;
            }
            echo json_encode($data, JSON_UNESCAPED_UNICODE);
            return $response;
    
});

These are my Endpoints on Android Studio (i am only trying, for now, the first one)

interface EndPoints {



    @GET("/RoomForStudents/api/anuncios/")
    fun getAnuncios(): Call<List<Anuncio>>

   /** @GET("/api/anuncios/{id}")
    fun getAnunciosById(@Path("id") id: Int): Call<Anuncio>*/
}

My ServiceBuilder (i already added the gson, to solve another error , about JSON malforming)

object ServiceBuilder {

   private val gson = GsonBuilder().setLenient().create()


    private val client = OkHttpClient.Builder().build()

    private val retrofit = Retrofit.Builder()
        /**.baseUrl("https://tneveda.000webhostapp.com/")*/
        .baseUrl("https://tneveda.000webhostapp.com/")
        .addConverterFactory(GsonConverterFactory.create(gson))
        .client(client)
        .build()

    fun<T> buildService(service: Class<T>): T {
        return retrofit.create(service)
    }
}

I think the problem is somehow with the format of the Data that is readed in my webService, because i made a test with this Dummy Data https://jsonplaceholder.typicode.com/users and it worked, however with the data of my WebService it doesn't work, however i am having troubling in finding a solution

Thank you

Just to add the result of the get endpoint of my webservice https://tneveda.000webhostapp.com/RoomForStudents/api/anuncios

EDIT

Noticed on postman, that after using my endpoints, i was getting the responde in html, and added this is the PHP file with the endpoints with SLIM/NOTORM ''' header("Content-Type: application/json; charset=UTF-8"); ''' Also changed JSON_UNESCAPED_UNICODE to JSON_PRETTY_PRINT

and now my response in the server is in JSON format and pretty

However it is still giving me the same error

CodePudding user response：

You should remove the last forward slash / from your @GET annotation.

@GET("/RoomForStudents/api/anuncios")
fun getAnuncios(): Call<List<Anuncio>>

As the last / is leading to a different endpoint, and your server is throwing a HttpNotFoundException.
