Alpaca Bug : Attribute Error

[prithviraj-gotepatil-algobulls]

Occurred while runnig PT and RT jobs.
Probable cause for this error, data in the queried time is not avaible at alpaca or alpaca is not allowing for trial users

Got this Error 2 times one for PT and one for RT, both on different strategies,
The Instrument given in both the cases was TSLA (this could be a probable cause too if TSLA hist data is not available at Alpaca)

This seems to be an issue from the Alpaca side. It hasn't occurred frequently in recent times, meaning it is probably fixed on the Alpaca end. We'll keep it open until we have a clear resolution here
