Summary: https://www.internalfb.com/tasks/?t=211442303 There was an error in running query on Prestissimo not Presto - "Scalar function presto.default.substr not registered with arguments: (JSON, BIGINT, BIGINT)". This is not due to missing function, as the function signature does not exist in Presto. It occurs when attempting to cast JSON as varchar of capped length.
