I tried to use the following call to search for different fund symbols. It was working using RIC, ISIN, but always got an error when using LipperID:
ek.get_symbology(["LP60000008"], from_symbol_type="RIC", to_symbol_type="LipperID")
It will fail using "from" or "to". I tried "lipperID", "LipperID", "Lipper ID", "Lipper_ID". I think the error message do not offer me a valid string for Lipper ID.
For the sample fund above the Lipper ID should be "60000008". i.e. the last 8 character in the RIC. It will be nice if a working sample using Lipper ID in get_symbology call can be provided.
