Android .I don't get data when using kotlinx serialization

Question

When creating the application, I had difficulties with kotlinx serialization. I wrote the code based on the article: https://vtsen.hashnode.dev/simple-rest-api-android-app-in-kotlin-various-http-client-library-implementations and https://www.valueof.io/blog/basic-auth-okhttp-retrofit-dagger Here is my code:

@Module
@InstallIn(SingletonComponent::class)
object AppModule {

    @Provides
    fun providesBaseUrl(): String = "https://api.github.com"

    private val loggingInterceptor = HttpLoggingInterceptor().apply {
        level = HttpLoggingInterceptor.Level.BODY
    }

    private val okHttpBuilder = OkHttpClient.Builder()
        .addInterceptor(loggingInterceptor)

    @Provides
    fun provideApiService(): ApiService {
        okHttpBuilder.addInterceptor(
            BasicAuthInterceptor()
        )

        val contentType = "application/json".toMediaType()

        return Retrofit.Builder()
            .baseUrl("https://api.github.com")
            .addConverterFactory(Json.asConverterFactory(contentType))
            .client(okHttpBuilder.build())
            .build()
            .create(ApiService::class.java)
    }

    @Provides
    @Singleton
    fun provideUserInfoRepository( mainService: ApiService): UserInfoRepository =UserInfoRepository(mainService)

    @Provides
    @Singleton
    fun provideGithubRepositoriesRepository( mainService: ApiService): GithubRepositoriesRepository =GithubRepositoriesRepository(mainService)

}

class BasicAuthInterceptor() : Interceptor {
    private val credentials: String = "Bearer My_Token"

    @Throws(IOException::class)
    override fun intercept(chain: Interceptor.Chain): Response {
        val request: Request = chain.request()
        val authenticatedRequest: Request = request.newBuilder()
            .header("Authorization", credentials).build()
        return chain.proceed(authenticatedRequest)
    }

I should get the answer in the form of JSON:

When I use GsonConverterFactory then I get the correct result:

return Retrofit.Builder()
            .baseUrl("https://api.github.com")
            .addConverterFactory(GsonConverterFactory.create())
            .client(okHttpBuilder.build())
            .build()
            .create(ApiService::class.java)
