const where = {
        office_no: 1999,
        status: 'APPLY,
        [Op.and]: [
            Sequelize.literal(`${property_master_no} member of (request_json->'$.property[*].property_master_no')`)
        ]
    }

    if (document_no) {
        where['no'] = {
            [Op.not]: document_no
        }
    }

I want to make [if] in [const where].

Sorry. I don’t have any idea. 🙂
