GSON is not mapping values with data class in kotlin

Hi I am using gson library to map values of response to model. I am doing it like this but it is not mapping values of response to model. I am getting list of 50 models but values in it is zero.

@Provides
@Singleton
fun provideRestApiHelper(
        okHttpClient: OkHttpClient,
        gson: Gson,
        rxJava2CallAdapterFactory: RxJava2CallAdapterFactory): RestApi {
    val builder = Retrofit.Builder()
            .baseUrl(BuildConfig.BASE_URL)
            .addCallAdapterFactory(rxJava2CallAdapterFactory)
            .addConverterFactory(GsonConverterFactory.create(gson))
    val retrofit = builder.client(okHttpClient).build()
    return retrofit.create(RestApi::class.java)
}

RestApi.kt

interface RestApi {

    @GET(ApiEndPoint.ENDPOINT_GITHUB_JOBS)
    fun getJobsApiCall(): Observable<List<JobsResponse>>
}

ApiHelperImpl.kt

class ApiHelperImpl @Inject constructor(private val restApi: RestApi) : ApiHelper {

    override fun getJobsApiCall(): Observable<List<JobsResponse>> {
        return restApi.getJobsApiCall()
    }
}

JobsResponse.kt

data class JobsResponse(

        @field:SerializedName("company_logo")
        val companyLogo: String?,

        @field:SerializedName("how_to_apply")
        val howToApply: String?,

        @field:SerializedName("created_at")
        val createdAt: String?,

        @field:SerializedName("description")
        val description: String?,

        @field:SerializedName("location")
        val location: String?,

        @field:SerializedName("company")
        val company: String?,

        @field:SerializedName("company_url")
        val companyUrl: String?,

        @field:SerializedName("id")
        val id: String?,

        @field:SerializedName("title")
        val title: String?,

        @field:SerializedName("type")
        val type: String?,

        @field:SerializedName("url")
        val url: String?
) : BaseResponse()

I am calling this API https://jobs.github.com/positions.json. Does anyone know what could be the issue ?

That's because you rely on auto-converted java code

remove @field:SerializedName changed it to @SerializedName

don't put them in to primary constructor

define them like this:

data class JobsResponse(){
@SerializedName("company_logo")
val companyLogo: String? = null


....

}
