Error on oracle.Bootstrap()

[chipchipzero]

As your tutorial, I've tried to create sample oracle project. Here is my main.go

package main

import (
  "time"

  framework "github.com/hyplabs/dfinity-oracle-framework"
  "github.com/hyplabs/dfinity-oracle-framework/models"
)

func main() {
  weatherApiKey := "WEATHER_API_KEY"
  weatherBitApiKey := "WEATHER_BIT_API_KEY"
  tokyoEndpoints := []models.Endpoint{
    {
      Endpoint: "http://api.weatherapi.com/v1/current.json?key="+weatherApiKey+"&q=Tokyo,JP",
      JSONPaths: map[string]string{
        "temperature_celsius": "$.current.temp_c",
      },
    },
    {
      Endpoint: "https://api.weatherbit.io/v2.0/current?key="+weatherBitApiKey+"&city=Tokyo&country=JP",
      JSONPaths: map[string]string{
        "temperature_celsius": "$.data[0].temp",
      },
    },
  }
  delhiEndpoints := []models.Endpoint{
    {
      Endpoint: "http://api.weatherapi.com/v1/current.json?key="+weatherApiKey+"&q=Delhi,IN",
      JSONPaths: map[string]string{
        "temperature_celsius": "$.current.temp_c",
      },
    },
    {
      Endpoint: "https://api.weatherbit.io/v2.0/current?key="+weatherBitApiKey+"&city=Delhi&country=IN",
      JSONPaths: map[string]string{
        "temperature_celsius": "$.data[0].temp",
      },
    },
  }
  config := models.Config{
    CanisterName:   "sample_oracle",
    UpdateInterval: 1 * time.Minute,
  }
  engine := models.Engine{
    Metadata: []models.MappingMetadata{
      {Key: "Tokyo", Endpoints: tokyoEndpoints},
      {Key: "Delhi", Endpoints: delhiEndpoints},
    },
  }
  oracle := framework.NewOracle(&config, &engine)
  oracle.Bootstrap()
  oracle.Run()
}

After run ./sample-oracle

Then I run this command dfx canister call sample_oracle get_map, it returns (null)

➜  sample_oracle git:(master) ✗ dfx canister status sample_oracle

So, I think there is error(s) somewhere on oracle.Bootstrap(), can not get weather data.
Please help! Thanks!
