For most symbols, the notebook code below works. However, for some symbols like NKLA, contracts returned by GetOptionContractList contain a different symbol. In NKLA case, VTIQ is returned. GetOptionHistory then causes the error:
No option type exists for underlying SecurityType: Base
I suspect VTIQ is a shell company for NLKA which allowed it to go public.
How can I retrieve the option data in a case like this?
Here is the notebook code:
qb = QuantBook()
equity = qb.AddEquity('NKLA', Resolution.Minute) # NKLA is translated to VTIQ
#equity = qb.AddEquity('AAPL', Resolution.Minute) # AAPL is not translated
contracts = qb.OptionChainProvider.GetOptionContractList(equity.Symbol,datetime(2021, 1, 13, 12, 10))
print(equity.Symbol,contracts[0].ID.Symbol)
option_history = qb.GetOptionHistory(contracts[0].ID.Symbol, datetime(2021, 1, 13, 12, 10))

The solution is to use the contract, instead of the symbol. So contract[0].ID.Symbol should be changed to contract[0].
