link tatamotors

https://www.alphavantage.co/query?function=time_series_daily_adjusted&symbol=tatamotors&outputsize=full&apikey=mcaf9b429i44328u

can please me why happening?

i've noticed alpha vantage when retrieving data list of stocks, response have empty body.

  1. are having error same stock tickers each time fetch data, or happening different tickers each time?
  2. what response body like?
  3. when did problem start? has been this, or intermittent?

it seems bug on end, , seems follow period of 500 server errors effect of "heroku app: application error". doesn't happen every day, , doesn't happen same stock ticker each time fetch data.

in short, it's server-side bug. hey, it's free service , it's pretty great.

since error doesn't happen same stock each time, added retry feature, , results in mostly-complete set of data on days when service buggy.
