Kindly provide more details about how you reached this issue. Would be great if you could share the piece of the code so that we can reproduce this error.

[rpbaltazar]

    def forecast(location)
      location_forecast = OpenWeather::Forecast.city(location)
      if location_forecast['cod'] == '200'
        forecast_to_use = get_closest_forecast location_forecast['list']
        build_weather_string location, forecast_to_use
      else
        build_error_message location
      end
    end

Nothing special.
I believe it might have to do with quotas and the openweather server answering with an error code and not parseable JSON.
If you take a closer look at the error that I pasted before,

JSON::ParserError: 757: unexpected token at '500

Seams that the server is answering you with 500 (internal server error) and then you try to parse it which causes an exception.
