How to convert the PermID to RICs?

I saw that when using the function ek.get_symbology, RICs, ISINs can be converted to PermID, however, it seems impossible to convert directly from permid to RICs

For example:

permid=['4295857664']
convertrics3=ek.get_symbology(permid, from_symbol_type='OAPermID', to_symbol_type=['RIC','ISIN'])
print(convertrics3)

(The description for the error: 2020-11-29 22:04:19,875 P[19480] [MainThread 13392] Can not process metadata for request: SymbologySearch.from - value doesn't fall in valid range: [RIC ISIN CUSIP SEDOL ticker lipperID IMO]

Is there any way to convert PermID to RICs, by other functions/instructions?

Can I use the permID instead of RICs to take historical time series data?

Thank you
