Hello,
Why isn't the field "EXPIR_DATE" consistently available for futures contracts (expired or not)?
The following gives the field value only for the active (non-expired) contract:
dfe, _ = ek.get_data(['MZNH20^2', 'MZNH20', 'MZNH21'], 'EXPIR_DATE')
InstrumentEXPIR_DATE0MZNH20^2<NA>1MZNH20<NA>2MZNH212021-03-17
