ConseilJS seems not support parameter type List Signature, see at https://github.com/Cryptonomic/ConseilJS/issues/261.
So I want to encode my parameter to JSON code that I can change parameterType from conseilJS.TezosParameterFormat.Michelson
to conseilJS.TezosParameterFormat.Micheline
. But I don't know how to encode my parameter to tezos required JSON.
