Sids whose price get not be found

Hi,

I would like to get daily price from EDI database which I have the subscription to. I found the Sids from the get_securities call, but the get_prices request gets 400 response with no history matches the query parameters message.

Examples:
exchange XSWX, sid: IB44501219
exchange XSES, sid: FIBBG000RKC136
and I think there are more.

Both of those sids are indexes and thus are not in the EDI equities data. They can be collected from Interactive Brokers, however.
