No proper documentation/example for PSI

I am trying to get matching score for query in an encrypted db but I can't seem to make it work. I keep getting

libc++abi: terminating with uncaught exception of type helib::LogicError: Index for column does not exist. Given index 1. Expected index in range [0, 1).

I have no idea what i'm doing wrong it maybe in in db data format or query format or parameters. If possible please provide a proper working example to make it easier to troubleshoot.
