I am currently confused about using the Tiingo news feed for live trading. It works in backtests but when I do live paper testing I get:

Runtime Error: Unable to locate exchange hours for Base-usa-TSLA.TiingoNews. in MarketHoursDatabase.cs:line 238

I checked if you need a paid subscription for Tiingo and while previous forum posts suggest that you do. The following image on the Tiingo news feed page suggests that it is also free for live trading. My question is, is this true and I have run into an error, or it is indeed a paid subscription?
