OkHttpClient doesn't add headers to requests

I m creating an android app and i m using retrofit to consume api webservices. my problem is when i add a header using annotation, it works.

@Headers("Authorization: jwt-token")
@POST("appusers-service/signin/identification")
suspend fun authentication(@Body body : LoginIdentificationDto.Params) : NetworkResponse<LoginIdentificationDto.Result, LoginIdentificationDto.Errors>

but when I use intercepters to add the header dynamically, it doesn’t work

@Provides
@Singleton
fun provideHttpClient() : OkHttpClient
{
    return OkHttpClient.Builder()
        .callTimeout(60, TimeUnit.SECONDS)
        .readTimeout(60, TimeUnit.SECONDS)
        .writeTimeout(60, TimeUnit.SECONDS)
        .connectTimeout(60, TimeUnit.SECONDS)
        .addNetworkInterceptor {
            
            val builder : Request.Builder = it.request().newBuilder()
            
            builder.addHeader(AUTHORIZATION_HEADER, "jwt-token")
            
            return@addNetworkInterceptor it.proceed(builder.build())
        }
        .build()
}

@Provides
@Singleton
fun provideRetrofit(httpClient : OkHttpClient, mapper : ObjectMapper) : Retrofit
{
    return Retrofit.Builder()
        .baseUrl(BASE_URL)
        .client(httpClient)
        .addCallAdapterFactory(NetworkResponseAdapterFactory())
        .addConverterFactory(JacksonConverterFactory.create(mapper))
        .build()
}

how can i solve this problem please?

class AuthInterceptor : Interceptor {

    @Throws(IOException::class)
    override fun intercept(chain: Interceptor.Chain): Response {
        val request = chain.request()
        val authenticatedRequest = request.newBuilder()
            .addHeader("Content-Type", "application/json")
            .addHeader("Authorization", UserData.getAuthToken())
            .build()
        return chain.proceed(authenticatedRequest)
    }
}

val ohHttpClient = OkHttpClient.Builder()
ohHttpClient.addInterceptor(AuthInterceptor())

return OkHttpClient.Builder()
        .callTimeout(60, TimeUnit.SECONDS)
        .readTimeout(60, TimeUnit.SECONDS)
        .writeTimeout(60, TimeUnit.SECONDS)
        .connectTimeout(60, TimeUnit.SECONDS)
        .addInterceptor {
            val builder : Request.Builder = it.request().newBuilder()
            builder.addHeader(AUTHORIZATION_HEADER, "jwt-token")
            return@addNetworkInterceptor it.proceed(builder.build())
        }
        .build()
